- * Name: sig_mqnotempty
- *
- * Description:
- * This function is equivalent to sigqueue(), but supports the messaging
- * system's requirement to signal a task when a message queue becomes
- * non-empty. It is identical to sigqueue(), except that it sets the
- * si_code field in the siginfo structure to SI_MESGQ rather than SI_QUEUE.
