The application or implementation before including
the header files. This is common practice and how
it is done in /usr/include/pthread.h on GNU/Linux.
http://man7.org/linux/man-pages/man3/pthread_attr_setaffinity_np.3.html
There are also other constants like thus __USE_XOPEN2K, __USE_BSD,
and __USE_XOPEN2K8 are pretty common. It is similar to the STDC
one but that's usually tripped by gcc, while these are application
choices on what library API standard to adhere to.
Sorry to sound pendantic but this is the common practice.
Yes, exactly this is why I asked. In the man page you have:
*#define _GNU_SOURCE */* See feature_test_macros(7) */
*#include <pthread.h>*
You use __USE_GNU.
