pthread_kill_other_threads_np(3) — Linux manual page



NAME         top

       pthread_kill_other_threads_np   -  terminate  all  other  threads  in

SYNOPSIS         top

       #include <pthread.h>

       void pthread_kill_other_threads_np(void);

DESCRIPTION         top

       pthread_kill_other_threads_np() has an effect only in the
       LinuxThreads threading implementation.  On that implementation,
       calling this function causes the immediate 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         top

       This function is a nonstandard GNU extension; hence the suffix "_np"
       (nonportable) in the name.

NOTES         top

       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
       implementation 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
       implementation does the right thing during an execve(2).)
