NAME
pthreadkill - send a signal to a thread SYNOPSIS
#include
int pthreadkill(pthreadt thread, int sig); Compile and link with -pthread. DESCRIPTION The pthreadkill() 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 per‐ formed; this can be used to check for the existence of a thread ID. RETURN VALUE On success, pthreadkill() returns 0; on error, it returns an error number, and no signal is sent. ERRORS EINVAL An invalid signal was specified. ESRCH No thread with the ID thread could be found.

POSIX.1-2001. NOTES
Signal dispositions are process-wide: if a signal handler is installed, the handler will be invoked in the thread thread, but if the disposi‐ tion of the signal is "stop", "continue", or "terminate", this action will affect the whole process.
