pthread_kill_other_threads_np — terminate all other threads in process
#include <pthread.h>
void
pthread_kill_other_threads_np( |
void); |
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 cancellation 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 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).)
