+ * Name: pthread_kill
+ *
+ * Description:
+ *   The pthread_kill() system call can be used to send any signal to a
+ *   thread.  See kill() for further information as this is just a simple
+ *   wrapper around the kill() function.
+ *
+ * Parameters:
+ *   thread - The id of the thread to receive the signal. Only positive,
+ *     non-zero values of 'thread' are supported.
+ *   signo - The signal number to send.  If 'signo' is zero, no signal is
+ *    sent, but all error checking is performed.
+ *
+ * Return Value:
+ *    On success the signal was send and zero is returned. On error one
+ *    of the following error numbers is returned.
+ *
+ *    EINVAL An invalid signal was specified.
+ *    EPERM  The thread does not have permission to send the
+ *           signal to the target thread.
+ *    ESRCH  No thread could be found corresponding to that
+ *           specified by the given thread ID
+ *    ENOSYS Do not support sending signals to process groups.
+ *
+ * Assumptions:
