.TH PTHREAD_KILL_OTHER_THREADS_NP 3 2017-09-15 "Linux" "Linux Programmer's Manual"
|
|
.SH NAME
|
|
pthread_kill_other_threads_np \- terminate all other threads in process
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #include <pthread.h>
|
|
.PP
|
|
.B void pthread_kill_other_threads_np(void);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
.BR 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 threads.
|
|
.\" .SH VERSIONS
|
|
.\" Available since glibc 2.0

.SH CONFORMING TO
|
|
This function is a nonstandard GNU extension;
|
|
hence the suffix "_np" (nonportable) in the name.
|
|
.SH NOTES
|
|
.BR pthread_kill_other_threads_np ()
|
|
is intended to be called just before a thread calls
|
|
.BR 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
|
|
.BR execve (2).
|
|
.PP
|
|
In the NPTL threading implementation,
|
|
.BR pthread_kill_other_threads_np ()
|
|
exists, but does nothing.
|
|
(Nothing needs to be done,
|
|
because the implementation does the right thing during an
|
|
.BR execve (2).)
