<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>raise</B>()
|
|
|
|
function sends a signal to the calling process or thread.
|
|
In a single-threaded program it is equivalent to
|
|
<P>
|
|
|
|
|
|
|
|
kill(getpid(), sig);
|
|
|
|
|
|
<P>
|
|
|
|
In a multithreaded program it is equivalent to
|
|
<P>
|
|
|
|
|
|
|
|
pthread_kill(pthread_self(), sig);
|
|
|
|
|
|
<P>
|
|
|
|
If the signal causes a handler to be called,
|
|
<B>raise</B>()
|
|
|
|
will return only after the signal handler has returned.

<A NAME="lbAE"> </A>
|
|
<H2>RETURN VALUE</H2>
|
|
|
|
<B>raise</B>()
|
|
|
|
returns 0 on success, and nonzero for failure.

<H2>NOTES</H2>

|
|
|
Since version 2.3.3, glibc implements
|
|
<B>raise</B>()
|
|
|
|
by calling
|
|
<B><A HREF="/cgi-bin/man/man2html?2+tgkill">tgkill</A></B>(2),
|
|
|
|
|
|
if the kernel supports that system call.
|
|
Older glibc versions implemented
|
|
<B>raise</B>()
|
|
|
|
using
|
|
<B><A HREF="/cgi-bin/man/man2html?2+kill">kill</A></B>(2).
