pthread_kill: poslat signál do vlákna

Originální popis anglicky: pthread_kill - send a signal to a thread

Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <signal.h>

int pthread_kill(pthread_t thread, int sig );

POPIS / INSTRUKCE

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.

NÁVRATOVÁ HODNOTA

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.

CHYBY / ERRORY

The pthread_kill() function shall 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.

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

The following sections are informative.

The pthread_kill() function provides a mechanism for asynchronously directing a signal at a thread in the calling process. This could be used, for example, by one thread to affect broadcast delivery of a signal to a set of threads.

Note that pthread_kill() only causes the signal to be handled in the context of the given thread; the signal action (termination or stopping) affects the process as a whole.

RATIONALE

None.

FUTURE DIRECTIONS

None.
