pthread_kill_other_threads_np(3)                      Library Functions Manual

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
       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.

       For an explanation of the terms used in this section, see

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

HISTORY
       glibc 2.0

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
       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).
