Uhmm.

Subject: Defect in XSH pthread_cond_timedwait()
Defect report from : Ulrich Drepper , Red Hat, Inc.
(Please direct followup comments direct to yyyyyyyyyyyyyy@xxxxxxxxxxxxx)
@ page 1033 line 32522 section pthread_cond_timedwait() objection {ud-cv-1}
Problem:
Defect code : 1. Error
The error section for pthread_cond_tiemdwait() and pthread_cond_wait()
currently says:
32518 ERRORS
32519 The pthread_cond_timedwait( ) function shall fail if:
32520 [ETIMEDOUT] The time specified by abstime to
pthread_cond_timedwait( ) has passed.
32521 The pthread_cond_timedwait( ) and pthread_cond_wait( ) functions may
fail if:
32522 [EINVAL] The value specified by cond, mutex, or abstime is
invalid.
There are a number of things wrong:
- pthread_cond_wait() has no abstime parameter;
- the recognition of an invalid abstime parameter must not be optional.
It isn't anywhere else.
Action:
Change the beginning of the ERRORS section above to:
ERRORS
The pthread_cond_timedwait( ) function shall fail if:
[ETIMEDOUT] The time specified by abstime to
pthread_cond_timedwait( ) has passed.
[EINVAL] The value specified by abstime is invalid.
The pthread_cond_timedwait( ) and pthread_cond_wait( ) functions may fail
if:
[EINVAL] The value specified by cond or mutex is invalid.
I.e., create an [EINVAL] case in the "shall" section.
