int \fBpthread_kill\fP(pthread_t \fBthread\fR,\fBsigno\fR);
.fi
.SH "DESCRIPTION"
.PP
This function is a standard POSIX threads function. \fBpthread_kill\fP sends signal \fBsigno\fR to the realtime thread \fBthread\fR previously created by a call to \fBpthread_create\fP. \fBpthread_kill\fP is a fast and deterministic function if called on threads running on the same processor as the calling thread or interrupt handler. \fBpthread_kill\fP can be used to send signals
to threads running on other than current CPU, but this is a more expensive
operation and there may be delays before the signal will be detected by
the target thread.
.SH "RETURN VALUE"
.PP
\fBpthread_kill\fP returns 0 on success and a non-zero error code on error.
.SH "ERRORS"
.IP "ESRCH" 10
No thread could be found corresponding to that specified by the given thread ID.
.SH "AUTHOR"
.PP

.SH "NOTES"
.PP
\fBpthread_kill\fP is safe to call from a signal handler, a
thread and from Linux kernel code.
\fBpthread_kill\fP is one of the primary means of sending
signals to the general purpose operating system (Linux). A call
\fBpthread_kill(\fBpthread_linux()\fR,\fBRTL_LINUX_MIN_SIGNA+n\fR)\fP for an integer value \fBn\fR will generate irq \fBn\fR in the Linux thread.
.PP
\fBpthread_kill(\fBpthread_linux()\fR,\fBRTL_SIG_SUSPEND_LINUX\fR)\fP sends the Linux thread on the
highest numbered processor an interrupt that will force Linux to suspend itself and
to tell the hardware to ignore all non-RTLinux interrupts (if possible). This
allows a processor on an SMP system to be dedicated to RTLinux. To restore
suspended Linux threads, in order, use RTL_SIG_RESTART_LINUX. The RESERVE_PROCESSOR config option must be selected when building RTLinux to enable this
feature.
