|
.SH NAME
|
|
|
|
pthread_kill_other_threads_np \- terminate all other threads in process
|
|
|
|
.SH SYNOPSIS
|
|
|
|
.nf
|
|
|
|
.B #include <pthread.h>
|
|

|
|
|
|

.SH DESCRIPTION
|
|
|
|
.BR 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.
|
|
|
|

|
|

The tendency in English, as prescribed in style guides like
Chicago MoS, is towards removing hyphens after prefixes
like "non-" etc.

.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).
|
|
|
|
|
|
|
|
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).)
