I have only been using SVID 3, POSIX, BSD 4.3 and ISO 9899.  The
documentation I have been using is Lewine's _POSIX Programmer's Guide_
for POSIX, AT&T's _System V Interface Definition Manual Third Edition
Volume 1_ for SVID 3, NET 2 for BSD 4.3 and various sources for
Standard C.  The function's existence and calling parameters should be
accurate from those sources.  I must confess that I haven't always
checked the returned error codes to see if they match exactly.

Rik suggested in another message that both POSIX and ISO 9899 were 
unnecessary.  The _POSIX Programmer's Guide_ dows include a number of
functions which are annotated as being required by Standard C, but are
not part of POSIX.  div(3) is an example picked entirely at random.
