  • Stuck in Infinite Loop while PostInvalidating

    - by Nicholas Roge
    I'm trying to test something, however, the loop I'm using keeps getting stuck while running. It's just a basic lock thread while doing something else before continuing kind of loop. I've double checked that I'm locking AND unlocking the variable I'm using, but regardless it's still stuck in the loop. Here are the segments of code I have that cause the problem: ActualGame.java: Thread thread=new Thread("Dialogue Thread"){ @Override public void run(){ Timer fireTimer=new Timer(); int arrowSequence=0; gameHandler.setOnTouchListener( new OnTouchListener(){ @Override public boolean onTouch(View v, MotionEvent me) { //Do something. if(!gameHandler.fireTimer.getActive()){ exitLoop=true; } return false; } } ); while(!exitLoop){ while(fireTimer.getActive()||!gameHandler.drawn); c.drawBitmap(SpriteSheet.createSingleBitmap(getResources(), R.drawable.dialogue_box,240,48),-48,0,null); c.drawBitmap(SpriteSheet.createSingleBitmap(getResources(),R.drawable.dialogue_continuearrow,32,16,8,16,arrowSequence,0),-16,8,null); gameHandler.drawn=false; gameHandler.postInvalidate(); if(arrowSequence+1==4){ arrowSequence=0; exitLoop=true; }else{ arrowSequence++; } fireTimer.startWait(100); } gameHandler.setOnTouchListener(gameHandler.defaultOnTouchListener); } }; thread.run(); And the onDraw method of GameHandler: canvas.scale(scale,scale); canvas.translate(((screenWidth/2)-((terrainWidth*scale)/2))/scale,((screenHeight/2)-((terrainHeight*scale)/2))/scale); canvas.drawColor(Color.BLACK); for(int layer=0;layer(less than)tiles.length;layer++){ if(layer==playerLayer){ canvas.drawBitmap(playerSprite.getCurrentSprite(), playerSprite.getPixelLocationX(), playerSprite.getPixelLocationY(), null); continue; } for(int y=0;y(less than)tiles[layer].length;y++){ for(int x=0;x(less than)tiles[layer][y].length;x++){ if(layer==0&&tiles[layer][y][x]==null){ tiles[layer][y][x]=nullTile; } if(tiles[layer][y][x]!=null){ runningFromTileEvent=false; canvas.drawBitmap(tiles[layer][y][x].associatedSprite.getCurrentSprite(),x*tiles[layer][y][x].associatedSprite.spriteWidth,y*tiles[layer][y][x].associatedSprite.spriteHeight,null); } } } } for(int i=0;i(less than)canvasEvents.size();i++){ if(canvasEvents.elementAt(i).condition(this)){ canvasEvents.elementAt(i).run(canvas,this); } } Log.e("JapaneseTutor","Got here.[1]"); drawn=true; Log.e("JapaneseTutor","Got here.[2]"); If you need to see the Timer class, or the full length of the GameHandler or ActualGame classes, just let me know.

  • c#, Internal, and Reflection

    - by cyberconte
    Duplicate of: Accessing internal members via System.Reflection? Is there a way to execute "internal" code via reflection? Here is an example program: using System; using System.Reflection; namespace ReflectionInternalTest { class Program { static void Main(string[] args) { Assembly asm = Assembly.GetExecutingAssembly(); // Call normally new TestClass(); // Call with Reflection asm.CreateInstance("ReflectionInternalTest.TestClass", false, BindingFlags.Default | BindingFlags.CreateInstance, null, null, null, null); // Pause Console.ReadLine(); } } class TestClass { internal TestClass() { Console.WriteLine("Test class instantiated"); } } } Creating a testclass normally works perfectly, however when i try to create an instance via reflection, I get a missingMethodException error saying it can't find the Constructor (which is what would happen if you tried calling it from outside the assembly). Is this impossible, or is there some workaround i can do?

  • T-SQL QUERY PROBLEM

    - by Sam
    Hi All, I have table called Summary and the data in the table looks like this: ID Type Name Parent 1 Act Rent Null 2 Eng E21-01-Rent Rent 3 Prj P01-12-Rent E21-Rent 1 Act Fin Null 2 Eng E13-27-Fin Fin 3 Prj P56-35-Fin E13-Fin I am writing a SP which has to pull the parent based on type. Here always the type Act has ID 1, Eng has ID 2 and Prj has ID 3. The type ACT parent is always NUll, type Eng parent is Act and type Prj parent is Eng Now I have table called Detail.I am writing a SP to insert Detail Table data to the Summary table. I am passing the id as parameter: I am having problem with the parent. How do I get that? I can always say when ID is 1 then parent is Null but when ID is 2 then parent is name of ID 1 similarly when ID is 3 then parent is name of ID2. How do I get that? Can anyone help me with this:

  • ReadFile doesn't work asynchronously on Win7 and Win2k8

    - by f0b0s
    According to MSDN ReadFile can read data 2 different ways: synchronously and asynchronously. I need the second one. The folowing code demonstrates usage with OVERLAPPED struct: #include <windows.h> #include <stdio.h> #include <time.h> void Read() { HANDLE hFile = CreateFileA("c:\\1.avi", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL); if ( hFile == INVALID_HANDLE_VALUE ) { printf("Failed to open the file\n"); return; } int dataSize = 256 * 1024 * 1024; char* data = (char*)malloc(dataSize); memset(data, 0xFF, dataSize); OVERLAPPED overlapped; memset(&overlapped, 0, sizeof(overlapped)); printf("reading: %d\n", time(NULL)); BOOL result = ReadFile(hFile, data, dataSize, NULL, &overlapped); printf("sent: %d\n", time(NULL)); DWORD bytesRead; result = GetOverlappedResult(hFile, &overlapped, &bytesRead, TRUE); // wait until completion - returns immediately printf("done: %d\n", time(NULL)); CloseHandle(hFile); } int main() { Read(); } On Windows XP output is: reading: 1296651896 sent: 1296651896 done: 1296651899 It means that ReadFile didn't block and returned imediatly at the same second, whereas reading process continued for 3 seconds. It is normal async reading. But on windows 7 and windows 2008 I get following results: reading: 1296661205 sent: 1296661209 done: 1296661209. It is a behavior of sync reading. MSDN says that async ReadFile sometimes can behave as sync (when the file is compressed or encrypted for example). But the return value in this situation should be TRUE and GetLastError() == NO_ERROR. On Windows 7 I get FALSE and GetLastError() == ERROR_IO_PENDING. So WinApi tells me that it is an async call, but when I look at the test I see that it is not! I'm not the only one who found this "bug": read the comment on ReadFile MSDN page. So what's the solution? Does anybody know? It is been 14 months after Denis found this strange behavior.

  • Returning NSNull from actionForLayer:forKey

    - by MrHen
    If I implement the CALayer delegate method actionForLayer:forKey I can return [NSNull null] to force the CALayer to not animate any changes. Unfortunately, [NSNull null] doesn't implement the CAAction delegate and XCode kicks out the following warning: warning: class 'NSNull' does not implement the 'CAAction' protocol Here is the method code: - (id<CAAction>)actionForLayer:(CALayer *)theLayer forKey:(NSString *)theKey { //This disables the animations when moving things around //Also, don't animate the selection box. It was doing weird things if(undoGroupStarted || theLayer == self.selectionBox) { return [NSNull null]; } else { return nil; } } Am I doing something wrong? Is returning [NSNull null] bad behavior? If so, what is another way to do what I am trying to do here? If not, how do I make the compiler happy?

  • Eclipse gives me a weird error when compiling...

    - by Legend
    I have this function which returns a datatype InetAddress[] public InetAddress [] lookupAllHostAddr(String host) throws UnknownHostException { Name name = null; try { name = new Name(host); } catch (TextParseException e) { throw new UnknownHostException(host); } Record [] records = null; if (preferV6) records = new Lookup(name, Type.AAAA).run(); if (records == null) records = new Lookup(name, Type.A).run(); if (records == null && !preferV6) records = new Lookup(name, Type.AAAA).run(); if (records == null) throw new UnknownHostException(host); InetAddress[] array = new InetAddress[records.length]; for (int i = 0; i < records.length; i++) { Record record = records[i]; if (records[i] instanceof ARecord) { ARecord a = (ARecord) records[i]; array[i] = a.getAddress(); } else { AAAARecord aaaa = (AAAARecord) records[i]; array[i] = aaaa.getAddress(); } } return array; } Eclipse complains that the return type should be byte[][] but when I change the return type to byte[][], it complains that the function is returning the wrong data type. I'm stuck in a loop. Does anyone know what is happening here?

  • Using Flot's Bar Graph in an Android WebView with Highlighting

    - by Nicholi
    The issue is unhighlighting bars which are no longer selected in a bar graph plotted by flot in a WebView on Android. Got no other issues drawing the actual graphs (which look beautiful for something so simple btw). I am not extremely knowledgeable in terms of javascript and web design/development but it seems little should have been needed, if it would just work!! :( I believe I'm following the Flot API correctly, if not someone please scream and yell at me. It seems to work just fine in a non-mobile browser at least. Hoping someone has done this before, but if not I've got the minimal necessary code to poke at your droids if inquiring minds would like to test. I've tested on two Nexus Ones (both 2.2.1), and have tried targeting with Andriod 1.5 and 2.2 SDKs (my intention is to target 1.5 if possible). I've been attempting to hack away at this for far too long on my own now. What happens: 1. Graph loads fine with bars. All bars unhighlighted. 2. Select a bar in graph, gets highlighted fine (and a tooltip is placed). 3. Select a different bar in graph, old bar is unhighlighted, old tooltip removed, new bar highlighted and tooltip placed (still no problems). 4. Click in the vast darkness of the graph which should then unhighlight the last bar... but it doesn't. I've tried disabling flot's autohighlight and manually doing it as well to no avail. Looking into flot itself and only getting down to drawOverlay() where the issue seems to begin... An even more disturbing bug(?) appears if the fill bar option is enabled in the graph, but I'd rather just forget about that for now. Also grabbed the latest version of flot from their svn (r290), but made no different from last public release (v0.6). As a complete guess I'm thinking it's an issue with WebKit's javascript implementation (or something specific to Nexus Ones, which wouldn't be so bad), but if there is any ugly hack to just get it to work I'm all ears. I've thrown the graph data directly into the html/js, rather than deal with showing all the code involved in the Java-javascript handler and callbacks. The simple html placed in 'assets/flot/test/' with jquery.js and jquery.flot.js: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script src="jquery.js"></script> <script src="jquery.flot.js"></script> <script id="source" language="javascript" type="text/javascript"> var lastItem = null; var plot = null; $(document).ready(function () { //window.testhandler.loadGraph(); // bind plotclick here $("#graphHolder").bind("plotclick", function (event, pos, item) { if (item) { var lastPoint = null; if (lastItem != null) lastPoint = lastItem.datapoint; if (!pointEquals(lastPoint, item.datapoint)) { //if (lastItem != null) // plot.unhighlight(lastItem.series, lastItem.datapoint); lastItem = item; $("#tooltip").remove(); //plot.highlight(item.series, item.datapoint); showTooltip(item.pageX, item.pageY, item.datapoint[1]); } } else if (lastItem != null) { plot.unhighlight(lastItem.series, lastItem.datapoint); // not unhighlighting anything //plot.unhighlight(); // doesn't work either, supposed to unhighlight everything lastItem = null; $("#tooltip").remove(); } }); GotGraph(); }); /** * Show a tooltip above bar in graph * @param {int} x Left coordinate of div * @param {int} y Top coordinate of div * @param {String} contents text to place in div */ function showTooltip(x, y, contents) { $('<div id="tooltip">' + contents + '</div>').css( { position: 'absolute', display: 'none', top: y, left: x, border: '1px solid #fdd', padding: '2px', 'background-color': '#fee', opacity: 0.80 }).appendTo("body").fadeIn(200); } /** * Draw the graph.

  • Singleton constructor question

    - by gillyb
    Hi, I created a Singleton class in c#, with a public property that I want to initialize when the Singleton is first called. This is the code I wrote : public class BL { private ISessionFactory _sessionFactory; public ISessionFactory SessionFactory { get { return _sessionFactory; } set { _sessionFactory = value; } } private BL() { SessionFactory = Dal.SessionFactory.CreateSessionFactory(); } private object thisLock = new object(); private BL _instance = null; public BL Instance { get { lock (thisLock) { if (_instance == null) { _instance = new BL(); } return _instance; } } } } As far as I know, when I address the Instance BL object in the BL class for the first time, it should load the constructor and that should initialize the SessionFactory object. But when I try : BL.Instance.SessionFactory.OpenSession(); I get a Null Reference Exception, and I see that SessionFactory is null... why?

  • Data model for timesheet to task and/or timesheet to project?

    - by John
    Let's say I want to make a simple project tracking system. A manager can create a project. Then he can create tasks for that project. Team members can record the hours they work for each task or for the project as a whole. Is the following design for the t_timesheet table a good idea? timesheet_id - primary key, autoincrement project_id - not null, foreign key constraint to t_project task_id - nullable, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal Or should I do something like this: timesheet_id - primary key, autoincrement task_id - not null, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal In the second option, I intend to always have a record in t_task labelled "miscellaneous items" with a foreign key to the relevant t_project record. Then I'll be able to track all hours for a project that aren't for any particular task. Are any of the ideas above good? What would be better?

  • Value isnt being saved in the strings

    - by Raptrex
    I'm trying to make a class where I put a key and value into the put method which puts the key in the k string array and value into the v string array, however it is not being saved in the array when I do get or display. For example: put(dan,30) get(dan) returns null display returns null null 10 times. Anyone know whats wrong? public class Memory { final int INITIAL_CAPACITY = 10; String[] k = new String[INITIAL_CAPACITY]; String[] v = new String[INITIAL_CAPACITY]; int count = 0; public Memory() { count = 0; } public int size() { return count; } public void put(String key, String value) { int a = 0; boolean found = false; for (int i = 0; i < k.length; i++) { //System.out.println("key is " + key.equals(k[i])); if (key.equalsIgnoreCase(k[i])) { v[i] = value; found = true; } if (found) break; a++; } //System.out.println(a == k.length); if (a == k.length); { k[count] = key; v[count] = value; //System.out.println(k[count] + " " + v[count]); count++; //System.out.println(count); } } public String get(String key) { String output = "a"; for(int i = 0; i < k.length; i++) { if(!key.equalsIgnoreCase(k[i])) { output = null; } else { output = v[i]; return output; } } return output; } public void clear() { for (int i = 0; i < k.length; i++) { k[i] = null; v[i] = null; } count = 0; } public void display() { for (int i = 0; i < k.length; i++) { System.out.println(k[i] + " " + v[i]); } } }

    - by steveo225
    I know this has been asked a ton, so my apologies. I have the following code, and cannot get the location, always a null response. I am trying to avoid a LocationListener in this instance because I am already using an update Service, and the location really doesn't have to be that fine, so the last known location is good enough. Thanks for the help. LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); String providers[] = {"gps", "network", "passive"}; Location loc = null; for(String x : providers) { loc = lm.getLastKnownLocation(x); if(loc != null) break; } if(loc != null) { // do something, never reached }

  • Mysql table data problem?

    - by DaTeNtImE
    I'm new to mysql and was wondering how can I add the users birthdate in the following HTML format to the MYSQL table data listed below? How would the structure look like for example email VARCHAR(80) NOT NULL,? Here is the HTML code below. <li><label>Date of Birth: </label> <label for="month">Month: </label> <select name="month" id="month"> <option value="January">January</option> <option value="February">February</option> <option value="March">March</option> <option value="April">April</option> <option value="May">May</option> <option value="June">June</option> <option value="July">July</option> <option value="August">August</option> <option value="September">September</option> <option value="October">October</option> <option value="November">November</option> <option value="December">December</option> </select> <label for="day">Day: </label> <select id="day" name="day"> <option value="0" selected="selected">Day</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> <option value="11">11</option> <option value="12">12</option> <option value="13">13</option> <option value="14">14</option> <option value="15">15</option> <option value="16">16</option> <option value="17">17</option> <option value="18">18</option> <option value="19">19</option> <option value="20">20</option> <option value="21">21</option> <option value="22">22</option> <option value="23">23</option> <option value="24">24</option> <option value="25">25</option> <option value="26">26</option> <option value="27">27</option> <option value="28">28</option> <option value="29">29</option> <option value="30">30</option> <option value="31">31</option> </select> <label for="year">Year: </label><input type="text" name="year" id="year" /></li> Here is the MySQL table data.

  • Drag Drop copy file

    - by Graham Warrender
    I've perhaps done something marginally stupid, but can't see what it is!! string pegasusKey = @"HKEY_LOCAL_MACHINE\SOFTWARE\Pegasus\"; string opera2ServerPath = @"Server VFP\"; string opera3ServerPath = @"O3 Client VFP\"; string opera2InstallationPath = null; string opera3InstallationPath = null; //Gets the opera Installtion paths and reads to the string opera*InstallationPath opera2InstallationPath = (string)Registry.GetValue(pegasusKey + opera2ServerPath + "System", "PathToServerDynamic", null); opera3InstallationPath = (string)Registry.GetValue(pegasusKey + opera3ServerPath + "System", "PathToServerDynamic", null); string Filesource = null; string[] FileList = (string[])e.Data.GetData(DataFormats.FileDrop, false); foreach (string File in FileList) Filesource = File; label.Text = Filesource; if (System.IO.Directory.Exists(opera3InstallationPath)) { System.IO.File.Copy(Filesource, opera3InstallationPath); MessageBox.Show("File Copied from" + Filesource + "\n to" + opera3InstallationPath); } else { MessageBox.Show("Directory Doesn't Exist"); } The user drags the file onto the window, I then get the installation path of an application which is then used as the destination for the source file.. When the application is runs, it throws the error directory not found. But surely if the directory doesn't exists is should step into the else statement? a simple application that is becoming a headache!!

  • Resharper code format linebreaks

    - by mizipzor
    Im trying to setup the code formatting in ReSharper. Limiting each line to a maximum count of characters, it seems to want to place casts on a separate line. Like so: string mystring = (string) MyStringConverter.convert(toconvert, typeof(string), null, null); I cant seem to be able to find the correct combination of settings to not have this on three lines. Im looking for something like this: string mystring = (string) MyStringConverter.convert( toconvert, typeof(string), null, null); Where the linebreak occurs is not that important, I guess I cant be to picky when I want to limit the line length. But three lines is a bit much. Does anyone know the/any correct combination of settings to make it only cut the line once?

  • Catching an exception that is nested into another exception

    - by Bernhard V
    Hi, I want to catch an exception, that is nested into another exception. I'm doing it currently this way: } catch (RemoteAccessException e) { if (e != null && e.getCause() != null && e.getCause().getCause() != null) { MyException etrp = (MyException) e.getCause().getCause(); ... } else { throw new IllegalStateException("Error at calling service 'beitragskontonrVerwalten'"); } } Is there a way to do this more efficient and elegant?

  • Objective C: Why is this code leaking?

    - by Johnny Grass
    I'm trying to implement a method similar to what mytunescontroller uses to check if it has been added to the app's login items. This code compiles without warnings but if I run the leaks performance tool I get the following leaks: Leaked Object # Address Size Responsible Library Responsible Frame NSURL 7 < multiple > 448 LaunchServices LSSharedFileListItemGetFSRef NSCFString 6 < multiple > 432 LaunchServices LSSharedFileListItemGetFSRef Here is the responsible culprit: - (BOOL)isAppStartingOnLogin { LSSharedFileListRef loginListRef = LSSharedFileListCreate(NULL, kLSSharedFileListSessionLoginItems, NULL); if (loginListRef) { NSArray *loginItemsArray = (NSArray *)LSSharedFileListCopySnapshot(loginListRef, NULL); NSURL *itemURL; for (id itemRef in loginItemsArray) { if (LSSharedFileListItemResolve((LSSharedFileListItemRef)itemRef, 0, (CFURLRef *) &itemURL, NULL) == noErr) { if ([[itemURL path] hasPrefix:[[NSBundle mainBundle] bundlePath]]) { [loginItemsArray release]; CFRelease(loginListRef); return YES; } } } [loginItemsArray release]; CFRelease(loginListRef); } return NO; }

  • camera picturecallback intent not work

    - by Simon
    After I take the photo, the program automatically goes back like onBackPressed(). When I remove the putExtra, the intent runs. When I put startActivity() after takePicture(), it transfers null data.... I just want to put the image data to another activity to have other use. How can it be achieved? private PictureCallback picture = new PictureCallback(){ @Override public void onPictureTaken(byte[] data, Camera camera) { // TODO Auto-generated method stub Intent intent = new Intent(CameraFilming.this, PhotoPreview.class); intent.putExtra("imageByte", data); //Picture data transfer to next activity startActivity(intent); } }; //take photo by pressing button private class captureBtnListener implements View.OnClickListener{ @Override public void onClick(View v){ capture.setOnClickListener(null); CountDownTimer timer = new CountDownTimer(10000, 1000){ @Override public void onTick(long millisUntilFinished) { // TODO Auto-generated method stub countdown.setText(millisUntilFinished/1000+""); } @Override public void onFinish() { // TODO Auto-generated method stub countdown.setText("0"); camera.takePicture(null, null, picture); } }; timer.start(); } } public class PhotoPreview extends Activity{ private RelativeLayout layout; private ImageView overlay, texture, face1, face2; @Override public void onCreate (Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.photo_preview); layout = (RelativeLayout)findViewById(R.id.preview_layout); byte[] data = getIntent().getByteArrayExtra("imageByte"); if (data == null){ Log.d("PhotoPreview", "no image data"); finish(); } Bitmap rawPhotoBitmap = BitmapFactory.decodeByteArray(data, 0, data.length); ImageProcess imgProcess = new ImageProcess(this); Bitmap resizedFace = imgProcess.scaleAccordingWidth(imgProcess.cropImage(rawPhotoBitmap, 840, 125, 440, 560), 77); face1 = new ImageView(this); face1.setImageBitmap(resizedFace); Log.d("testing", "testing"); } }

  • Creating a Group of Groups in Django

    - by Greg
    I'm creating my own Group model; I'm not referring to the builtin Group model. I want each hroup to be a member of another group (it's parent), but there is the one "top" group that doesn't have a parent group. The admin interface won't let me create a group without entering a parent. I get the error personnel_group.parent_id may not be NULL. My Group model looks like this: class Group(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey('self', blank=True, null=True) order = models.IntegerField() icon = models.ImageField(upload_to='groups', blank=True, null=True) description = models.TextField(blank=True, null=True) How can I accomplish this? Thanks.

  • Interesting LinqToSql behaviour

    - by Ben Robinson
    We have a database table that stores the location of some wave files plus related meta data. There is a foreign key (employeeid) on the table that links to an employee table. However not all wav files relate to an employee, for these records employeeid is null. We are using LinqToSQl to access the database, the query to pull out all non employee related wav file records is as follows: var results = from Wavs in db.WaveFiles where Wavs.employeeid == null; Except this returns no records, despite the fact that there are records where employeeid is null. On profiling sql server i discovered the reason no records are returned is because LinqToSQl is turning it into SQL that looks very much like: SELECT Field1, Field2 //etc FROM WaveFiles WHERE 1=0 Obviously this returns no rows. However if I go into the DBML designer and remove the association and save. All of a sudden the exact same LINQ query turns into SELECT Field1, Field2 //etc FROM WaveFiles WHERE EmployeeID IS NULL I.e. if there is an association then LinqToSql assumes that all records have a value for the foreign key (even though it is nullable and the property appears as a nullable int on the WaveFile entity) and as such deliverately constructs a where clause that will return no records. Does anyone know if there is a way to keep the association in LinqToSQL but stop this behaviour. A workaround i can think of quickly is to have a calculated field called IsSystemFile and set it to 1 if employeeid is null and 0 otherwise. However this seems like a bit of a hack to work around strange behaviour of LinqToSQl and i would rather do something in the DBML file or define something on the foreign key constraint that will prevent this behaviour.

  • error handling strategies in C?

    - by Leo
    Given the code below: typedef struct {int a;} test_t; arbitrary_t test_dosomething(test_t* test) { if (test == NULL) { //options: //1. print an error and let it crash //e.g. fprintf(stderr, "null ref at %s:%u", __FILE__, __LINE__); //2. stop the world //e.g. exit(1); //3. return (i.e. function does nothing) //4. attempt to re-init test } printf("%d", test->a); //do something w/ test } I want to get a compiler error if test is ever NULL, but I guess that's not possible in C. Since I need to do null checking at runtime, what option is the most proper way to handle it?
