pthread_kill_other_threads_Library Functions Mpthread_kill_other_threads_np(3)
NAME
pthread_kill_other_threads_np - terminate all other threads in process
LIBRARY
POSIX threads library (libpthread, -lpthread)
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 cancelation state and cancelation
type of the to-be-terminated threads are ignored, and the cleanup han-
dlers are not called in those threads.
ATTRIBUTES
For an explanation of the terms used in this section, see at-
tributes(7).

STANDARDS
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 de-
signed to address a limitation in the obsolete LinuxThreads implementa-
tion whereby the other threads of an application are not automatically
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 im-
plementation does the right thing during an execve(2).)
