pthread_kill: send a signal to a thread
PROLOGThis manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
pthread_kill - send a signal to a thread
The pthread_kill() function shall request that a signal be delivered to the specified thread.
The pthread_kill() function shall fail if:
- No thread could be found corresponding to that specified by the given thread ID.
The value of the sig argument is an invalid or unsupported signal
The pthread_kill() function shall not return an error code of [EINTR].
The pthread_kill() function provides a mechanism for asynchronously directing a signal at a thread in the calling process. This could be used, for example, by one thread to affect broadcast delivery of a signal to a set of threads.
