Interpretation Request #13
Topic: sigevent structure Relevant Clauses: 220.127.116.11 (IEEE Std 1003.1b-1993)
Clause --None in P1003.1c D10, corresponding section in IEEE Std 1003.1b-1993 is 18.104.22.168 The behavior is specified when a sigevent structure of type SIGEV_NONE or type SIGEV_SIGNAL is passed. POSIX.1c does not specify what the behavior is if the sigevent structure specifies SIGEV_THREAD. The behavior needs to be specified. According to the current definitions, these functions are not required to support SIGEV_THREAD, even if POSIX_THREADS is defined. They define SIGEV_SIGNAL AND SIGEV_NONE, but not SIGEV_THREAD.
This is a duplicate. See Interpretation #3, part 13.
