NAME

pthread_kill - send a signal to a thread  

SYNOPSIS

#include <signal.h>

int pthread_kill(pthread_t thread, int sig);

Compile and link with -pthread.  

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.  

ERRORS

ESRCH
No thread with the ID thread could be found.
EINVAL
An invalid signal was specified.
 

CONFORMING TO

POSIX.1-2001.  

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.
