pthread_kill - send a signal to a thread
#include <signal.h> int pthread_kill(pthread_t thread, int sig); Compile and link with -pthread.
The pthread_kill() function sends the signal sig to thread, a thread in the same process as the caller. The signal is asynchronously directed to thread. If sig is 0, then no signal is sent, but error checking is still performed; this can be used to check for the existence of a thread ID.
On success, pthread_kill() returns 0; on error, it returns an error number, and no signal is sent.
EINVAL An invalid signal was specified. ESRCH No thread with the ID thread could be found.
Signal dispositions are process-wide: if a signal handler is installed, the handler will be invoked in the thread thread, but if the disposition of the signal is "stop", "continue", or "terminate", this action will affect the whole process.
