Synopsis¶

#include <signal.h>

int pthread_kill(pthread_t thread, int sig);

Status¶

Implemented

Conformance¶

IEEE Std 1003.1-2017

Description¶

The pthread_kill() function shall request that a signal be delivered to the specified thread.

As in kill(), if sig is zero, error checking shall be performed, but no signal shall actually be sent.

Return value¶

Upon successful completion, the function shall return a value of zero. Otherwise, the function shall return an error number. If the pthread_kill() function fails, no signal shall be sent.

Errors¶

The pthread_kill() function shall fail if:

EINVAL - The value of the sig argument is an invalid or unsupported signal number.

The pthread_kill() function shall not return an error code of EINTR.
