Changeset 18840 for trunk/psModules/src/objects/pmSourceIO_OBJ.c

Timestamp:

Jul 31, 2008, 2:46:04 PM (18 years ago)

Author:

Message:

Check return value of fwrite (to get around a compiler warning
"ignoring return value of 'fwrite', declared with attribute
warn_unused_result"). Not sure I'm checking it against the right
value, but I figure we rarely, if ever, use this function.
