        Defect report from : Andrew Josey , The Open Group

(Please direct followup comments direct to yyyyyyyyyyyyyy@xxxxxxxxxxxxx)

@ page 294 line 9523 section errno objection {errno.iso.c.7.5}

Problem:

Edition of Specification (Year): 2003

Defect code :  1. Error


The errno man page misses some important information from the ISO C standard. 
This can lead to a misinterpretation of the requirements of when to set errno. 
Since this standard defers to ISO C we should add clarification text in the 
next TC.

Action:

Add to end of paragraph 2

"The value of errno may be set to non-zero by a function call whether or not 
there is an error, provided the use of errno is not documented for the function 
in IEEE Std 1003.1-2001"
