.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.

|
.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.
