This group is for discussion of the C language as defined by the
international C standard. Please don't post non-standard code here. Only
5 of those headers are standard.

This is also not a source code repository, so don't post code just to be
posting code. Only do it if you have a question or comment (relating to
the C language) about the code.

Stop right here! What made you think that C code littered with
non-standard extensions to the language could ever be topical in
comp.lang.c?

Please read the c.l.c welcome-message

http://www.angelfire.com/ms3/bchambless0/welcome_to_clc.html

and the c.l.c-faq

http://www.eskimo.com/~scs/C-faq/top.html

before posting here. Thank you very much.

BTW, what was your question?
