Interpretation Request: (Defect Report)

(This request raised on behalf of the X/Open Base Working group)

Which header is the  function pthread_atfork() defined in?
Should it be pthread.h. At the moment this
has been ommitted from that header. Was this intentional?

Interpretation response
------------------------
The P1003.1b-1993 standard, to which P1003.1c is an amendment, on page 39
section 2.7.3 lines 1119 to 1121, states that "if a function is not listed
below, it shall have its prototype appear in <unistd.h>..".  pthread_atfork is
not listed, so the standard is clear that it shall be listed in <unistd.h>.

Rationale
-------------
None.
