[PATCH 1/1] v2: Implement Condclockwait and Test
Matt Joyce
mfjoyce2004 at gmail.com
Thu Aug 19 16:20:23 UTC 2021
Added implementation of the pthread_cond_clockwait()
method to cpukit/posix/src/condclockwait.c. Additional
logic added to condwaitsupp.c to implement new method.
pthread_cond_clockwait() has been added to the Issue 8
POSIX Standard.
psxcond03 test added to testsuites/psxtests to test the
newly added method.
