• How do I declare a pipe in a header file? (In C)

  - by Kyle

  I have an assignment in which I need to declare a pipe in a header file. I really have no idea how to do this. It might be a really stupid question and I might be missing something obvious. If you could point me in the right direction I would greatly appreciate it. Thanks for your time.

• How do I use PHP to grab the name of the file?

  - by Sam

  Hi, what I want to do is PHP to look at the url and just grab the name of the file, without me needing to enter a path or anything (which would be dynamic anyway). E.G. http://google.com/info/hello.php, I want to get the 'hello' bit. Help? Thanks.

• How to directly access a certain part of a text file in g++?

  - by Phenom

  I have a text file containing a number of records. Each record is stored on a single line that is 100 characters long. Let's say I want to directly access the nth record. I could do it using a for loop, reading in n lines until I get to the record. But how could I access it directly?

• Handling macro redefinition without modifying .h files ... C / C++ language

  - by user310119

  Background: Let assume that I have two header files a.h and b.h. a.h contains: #define VAR 1 b.h contains: #define VAR 2 Note: The name of both of the macro is same. Let say I have some file myFile.c which includes both of the header files i.e. a.h and b.h. When I try to access VAR, I get a redefinition error of VAR. In order to resolve this problem, I inserted #ifndef VAR statement in both a.h and b.h files to prevent this error. a.h file becomes #ifndef VAR #define VAR 1 #endif b.h file becomes #ifndef VAR #define VAR 2 #endif Note: The header file can contain multiple macros, not just one macro. Problem: Let's assume that a.h and b.h files are obtained from third party library. These files don't contain #ifndef VAR statement. I am not allowed to change their header files. Can I resolve macro 'VAR' redefinition error in myFile.c or myFile.cpp file which uses VAR macro? I know I #undef VAR can be used to undefine a macro VAR. How can I selectively include VAR later in my program? i.e. on line 10 of myFile.c code I should be able to refer to VAR definition from a.h file, on line 15 of my code I should be able to refer to VAR from b.h file and on line 18 again I should be able to refer to VAR from a.h file. In short, am I able to do macro polymorphism ? Given a name of header file, it should refer to macro definition present in that file. I thought of using namespace trick to resolve an issue. Define first header file in namespace first and second header file in namespace second. I tried defining two namespaces. First namespace contains #include a.h and second namespace contains b.h. However, namespace trick does not work with macro. When I tried to access firstns::VAR, compiler reports an error message. Can you please suggest some way?

• Treating a file of Java floats as a lazy Clojure sequence.

  - by Cumbayah

  Hi; What would be an ideomatic way in Clojure to get a lazy sequence over a file containing float values serialized from Java? (I've toyed with a with-open approach based on line-reading examples but cannot seem to connect the dots to process the stream as floats.) Thanks.

• How do I copy a version of a single file from one git branch to another?

  - by madlep

  I've got two branches that are fully merged together. However, after the merge is done, I realise that one file has been messed up by the merge (someone else did an auto-format, gah), and it would just be easier to change to the new version in the other branch, and then re-insert my one line change after bringing it over into my branch. So what's the easiest way in git to do this?

• How to read file.xml from resources to NSString with format?

  - by falkon

  Actually I have such a code: NSString *path = [[NSBundle mainBundle] pathForResource: @"connect" ofType: @"xml"]; NSError *error = nil; NSString *data = [NSString stringWithContentsOfFile: path encoding: NSUTF8StringEncoding error: &error]; NSString *message = [NSString stringWithFormat:data, KEY, COUNTRY_ID]; which reads the connect.xml from resources. But on the formating the string (message) APP quits without displaying any errors. How can I read file.xml from resources to NSString with format?
