pthread_sigqueue - queue a signal and data to a thread
#include <signal.h> #include <pthread.h> int pthread_sigqueue(pthread_t thread, int sig, const union sigval value);
Compile and link with
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
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.
On success, pthread_sigqueue() returns 0; on error, it returns an error number.
The pthread_sigqueue() function first appeared in glibc 2.11.
For an explanation of the terms used in this section, see attributes(7).
This function is a GNU extension.
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.
