| | pthread_kill - send a signal to a thread |
SYNOPSIS
| |
cc -mt [ flag... ] file... -lpthread [ -lrt library... ]
#include <signal.h>
#include <pthread.h> int pthread_kill(pthread_t thread, int sig); |
| |
The pthread_kill() function is used to request that a signal be delivered to the specified thread.
As in kill(), if sig is 0, error checking is performed but no signal is actually sent.
|
| |
Upon successful completion, the function returns a value of 0. Otherwise the function returns an error number. If the pthread_kill() function fails, no signal
is sent.
|
| |
The pthread_kill() function will fail if:
-
ESRCH
- No thread could be found corresponding to that specified by the given thread ID.
-
EINVAL
- The value of the sig argument is an invalid or unsupported signal number.
