PTHREAD_KILL_OTHER_THREADS_NP(3) Linux Programmer's Manual PTHREAD_KILL_OTHER_THREADS_NP(3)
pthread_kill_other_threads_np - terminate all other threads in process
pthread_kill_other_threads_np() only has an effect 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 cancel-
lation type of the to-be-terminated threads are ignored, and the cleanup handlers are not called in those threads.
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 automati-
cally 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).)
