Section (3) pthread_kill_other_threads_np
pthread_kill_other_threads_np — terminate all other threads in process
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
For an explanation of the terms used in this section, see attributes(7).
This function is a nonstandard GNU extension; hence the suffix _np (nonportable) in the name.
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).)
