This 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.
The pthread_kill() function shall fail if:
EINVAL The value of the sig argument is an invalid or unsupported
The pthread_kill() function shall not return an error code of
The following sections are informative.
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.
Note that pthread_kill() only causes the signal to be handled in the
context of the given thread; the signal action (termination or
stopping) affects the process as a whole.
