Имя (Name)
pthread_sigqueue - queue a signal and data to a thread
Синопсис (Synopsis)
#include <signal.h>
#include <pthread.h>
int pthread_sigqueue(pthread_t thread, int sig,
const union sigval value);
Compile and link with -pthread.

feature_test_macros(7)):
pthread_sigqueue():
_GNU_SOURCE
Описание (Description)
The pthread_sigqueue() function performs a similar task to
sigqueue(3), but, rather than sending a signal to a process, it
sends a signal to a thread in the same process as the calling
thread.
The thread argument is the ID of a thread in the same process as
the caller. The sig argument specifies the signal to be sent.
The value argument specifies data to accompany the signal; see
sigqueue(3) for details.
Возвращаемое значение (Return value)
On success, pthread_sigqueue() returns 0; on error, it returns an
error number.
Ошибки (Error)
EAGAIN The limit of signals which may be queued has been reached.
(See signal(7) for further information.)
EINVAL sig was invalid.
ENOSYS pthread_sigqueue() is not supported on this system.
ESRCH thread is not valid.
Версии (Versions)
The pthread_sigqueue() function first appeared in glibc 2.11.

Примечание (Note)
The glibc implementation of pthread_sigqueue() gives an error
(EINVAL) on attempts to send either of the real-time signals used
internally by the NPTL threading implementation. See nptl(7) for
details.
