NAME         top

       pthread_kill_other_threads_np - terminate all other threads in
       process

LIBRARY         top

       POSIX threads library (libpthread, -lpthread)

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
       cancelation state and cancelation type of the to-be-terminated
       threads are ignored, and the cleanup handlers are not called in
       those threads.

VERSIONS         top

       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).)

STANDARDS         top

       GNU; hence the suffix "_np" (nonportable) in the name.

HISTORY         top

       glibc 2.0

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).
