PTHREAD_KILL_OTHER_THREADS_NP(3) Linux Programmer's Manual 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 function causes the imme‐
diate termination of all threads in the application, except the calling thread. The cancellation state and cancellation 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 lim‐
itation in the obsolete LinuxThreads implementation whereby the other threads of an application are not automatically terminated (as POSIX.1-2001 requires) dur‐
ing 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).)
