.TH PTHREAD_KILL_OTHER_THREADS_NP 3 LinuxThreads

.SH NAME
pthread_kill_other_threads_np \- terminate all threads in program except calling thread

.SH SYNOPSIS
#include <pthread.h>

void pthread_kill_other_threads_np(void);

.SH DESCRIPTION
!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! functions,
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 terminated threads.

!pthread_cancel!(3).

.SH BUGS

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 killed.
