pthread_sigqueue - queue a signal and data to a thread
#include <pthread.h> int pthread_sigqueue(pthread_t *thread, int sig, const union sigval value); Compile and link with -pthread. Feature Test Macro Requirements for glibc (see feature_test_macros(7)): pthread_sigqueue(): _GNU_SOURCE
The pthread_sigqueue() function performs a similar task to sigqueue(3), but, rather than sending a signal to another process, it sends a signal to another thread in the same process as the calling thread. The thread argument is the ID of another 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.
On success, pthread_sigqueue() returns 0; on error, it returns an error number.
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.
The pthread_sigqueue() function first appeared in glibc 2.11.
This function is a GNU extension.
