man:pthread_kill_other_threads_np
PTHREAD_KILL_OTHER_THREADS_Linux Programmer's PTHREAD_KILL_OTHER_THREADS_NP(3)
NAME
pthread_kill_other_threads_np - terminate all other threads in process
SYNOPSIS
#include <pthread.h>
void pthread_kill_other_threads_np(void);
DESCRIPTION
pthread_kill_other_threads_np() has an effect only in the LinuxThreads threading implementation. On that implementation, calling this func- tion causes the immediate termination of all threads in the applica- tion, except the calling thread. The cancellation state and cancella- tion type of the to-be-terminated threads are ignored, and the cleanup handlers are not called in those threads.

CONFORMING TO
This function is a nonstandard GNU extension; hence the suffix "_np" (nonportable) in the name.
NOTES
pthread_kill_other_threads_np() is intended to be called just before a thread calls execve(2) or a similar function. This function is designed to address a limitation in the obsolete LinuxThreads implemen- tation whereby the other threads of an application are not automati- cally terminated (as POSIX.1-2001 requires) during execve(2).
In the NPTL threading implementation, pthread_kill_other_threads_np() exists, but does nothing. (Nothing needs to be done, because the implementation does the right thing during an execve(2).)
