pthread_kill_other_threads_np - terminate all threads in program except calling thread
pthread_kill_other_threads_np is a non-portable LinuxThreads extension. It causes all
threads in the program to terminate immediately, except the calling thread which proceeds
normally. It is intended to be called just before a thread calls one of the exec func-
tions, e.g. execve(2).
Termination of the other threads is not performed through pthread_cancel(3) and completely
bypasses the cancellation mechanism. Hence, the current settings for cancellation state
and cancellation type are ignored, and the cleanup handlers are not executed in the termi-

According to POSIX 1003.1c, a successful exec* in one of the threads should terminate
automatically all other threads in the program. This behavior is not yet implemented in
LinuxThreads. Calling pthread_kill_other_threads_np before exec* achieves much of the
same behavior, except that if exec* ultimately fails, then all other threads are already
