Desired Action: After applying bug 1636, change:<blockquote>If there are any pending unblocked signals after the call to <i>pthread_sigmask</i>(), at least one of those signals shall be delivered before the call to <i>pthread_sigmask</i>() returns.</blockquote>to:<blockquote>If the argument <i>set</i> is not a null pointer and the change made to the currently blocked set of signals causes any pending signals to become unblocked, at least one of those signals shall be delivered before the call to <i>pthread_sigmask</i>() returns.</blockquote> ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2023-05-23 09:43 geoffclare New Issue 2023-05-23 09:43 geoffclare Name => Geoff Clare 2023-05-23 09:43 geoffclare Organization => The Open Group 2023-05-23 09:43 geoffclare Section => pthread_sigmask() 2023-05-23 09:43 geoffclare Page Number => 1734 2023-05-23 09:43 geoffclare Line Number => 56243 2023-05-23 09:43 geoffclare Interp Status => --- ======================================================================
