• Why thread specific data is required in pthread ?

  - by user504542

  Hi As i know, all the threads share memory location. For example a global variable changes in one thread will reflect in another thread. Since each thread has its own stack, the local variables that are created inside the thread is unique. In this case, why do we need to go for thread specific data mechanism?. Can't it be achieved by auto storage varibles inside the thread function ? Kindly clarify!!!. BR Rj

• when to use const char *

  - by djones2010

  If i have a function api that expects a 14 digit input and returns a 6 digit output. I basically define the input as a const char *. would that be the correct and safe thing to do? also why would I not want to just do char * which I could but it seems more prudent to use const char * in that case especially since its an api that i am providing. so for different input values I generate 6 digit codes.

• What makes C faster than Python?

  - by Chris

  I know this is probably a very obvious answer and that I'm exposing myself to less-than-helpful snarky comments, but I don't know the answer so here goes. If Python compiles to bytecode at runtime, is it just that initial compiling step that takes longer? If that's the case wouldn't that just be a small upfront cost in the code (ie if the code is running over a long period of time, do the differences between C and python diminish?)

• Linux: Can Recvmsg be used to receive the IP_TOS of every incoming packet

  - by Mayutan

  Can one use recvmsg() to obtain the IP_TOS field of every incoming packet or does it just show the IP_TOS value that is set for the particular socket. If not, does anyone know of a solution to obtain the IP_TOS values of every incoming packets. I am using a UDP application and therefore do not get to view the IP_TOS field at the application layer as is the case with TCP. Thanks.

• Gain Access to Mouse Clicks in C# Component

  - by Jason

  I am using the ScintillaNET component and I am attempting to capture clicks in the margin, as this will determine how I respond. Unfortunately, the margins capture the mouse events (and don't provide a way, from what I can see, to get the click information - number of clicks, mouse button clicked, etc). If this is indeed the case (I am not able to get that info directly), what is another way of capturing what the mouse is doing before the MarginClick event is fired? Thanks for any help!

• What's the consequence when Core Data detects an optimistic locking failure when trying to save?

  - by dontWatchMyProfile

  I get it: When a managed object context saves, the snapshots of all edited objects are compared against the values in the persistent store to see if the PS has changed since the snapshot was made. If it did change, then there's a conflict and optimistic locking failed, according to Apple. But now, what's the consequence of this? What happens next? What are my options in this case?

For Example: At the same time: Customer1 and Customer2 booked for a standard room which only has 1 room available. (The Room availability will display that there is still 1 room available). And then they hit the 'confirm' button at the same time.

• Removing [nid:n] in nodereference autocomplete

  - by AK

  Using the autocomplete field for a cck nodereference always displays the node id as a cryptic bracketed extension: Page Title [nid:23] I understand that this ensures that selections are unique in case nodes have the same title, but obviously this is a nasty thing to expose to the user. Has anyone had any success in removing these brackets, or adding a different unique identifier?
