I agree with you that the C standard is the authorative resource here.
However, I just checked the Single Unix specification
( http://www.rdg.opengroup.org:80/onlinepubs/7908799/ ), and discovered
for fwrite():

          The fwrite() function returns the number of members
     successfully written, which may be less than nitems if a write error
                                                        ^ note no `only' here!
     is encountered. If size or nitems is 0, fwrite() returns 0 and the
     state of the stream remains unchanged. Otherwise, if a write error
     occurs, the error indicator for the stream is set and errno is set
     to indicate the error.

So it appears to me that there is a conflict of standards here :-(.
What can be done to resolve such a conflict ?  Is it advisable to
contact the Open Group about it ?

Wolfram.
