pthread_main_np – identify the initial thread

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES SEE ALSO AUTHORS

POSIX Threads Library (libpthread, -lpthread)

#include <pthread_np.h>

int
pthread_main_np(void);

The pthread_main_np() function is used in userland threads environment to identify the initial thread. Its semantics is similar to the Solaris's thr_main() function.

The pthread_main_np() function returns 1 if the calling thread is the initial thread, 0 if the calling thread is not the initial thread, and -1 if the thread's initialization has not yet completed.
