<H2>DESCRIPTION</H2>
|
|
|
|
<B>pthread_kill_other_threads_np</B>()
|
|
|
|
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 threads.

<H2>CONFORMING TO</H2>
|

|

This function is a nonstandard GNU extension;
|
|
hence the suffix "_np" (nonportable) in the name.

<H2>NOTES</H2>
|
|
|
|
<B>pthread_kill_other_threads_np</B>()
|
|
|
|
is intended to be called just before a thread calls
|
|
<B><A HREF="/cgi-bin/man/man2html?2+execve">execve</A></B>(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
|
|
<B><A HREF="/cgi-bin/man/man2html?2+execve">execve</A></B>(2).
|
|
|
|
<P>
|
|
|
|
In the NPTL threading implementation,
|
|
<B>pthread_kill_other_threads_np</B>()
|
|
|
|
exists, but does nothing.
|
|
(Nothing needs to be done,
|
|
because the implementation does the right thing during an
|
|
