DESCRIPTION
The pthread_kill() function
sends the signal sig
to thread, another
thread in the same process as the caller. The signal is
asynchronously directed to thread.
If sig is 0, then
no signal is sent, but error checking is still performed;
this can be used to check for the existence of a thread
ID.
RETURN VALUE
On success, pthread_kill()
returns 0; on error, it returns an error number, and no
signal is sent.
NOTES
Signal dispositions are process-wide: if a signal handler
is installed, the handler will be invoked in the thread
thread, but if the
disposition of the signal is "stop", "continue", or
"terminate", this action will affect the whole process.
