how to set a threadname in MacOSX

In Windows, it is possible to set the threadname via this code. The threadname is then shown in debuggers.

In MacOSX, I have seen several hints which indicates that there are threadnames. I think the class NSThread also has a name-attribute. My go开发者_如何学Cal is that I can set the threadname in my C++ application and see it in Xcode/gdb.

I recommend the following:

[[NSThread currentThread] setName:@"My thread name"]; // For Cocoa  
pthread_setname_np("My thread name"); // For GDB.

(You'll need to include pthread.h) Works a treat in XCode 3.2.3 (at least for iPhone development)

Which version of Xcode are you using? Thread names are only supported in Mac OS X 10.6 and Xcode 3.2.
