As Jonathan says, you should specify what system you're using. – Matthew Flaschen Dec 29 '10 at 04:21

1Also, strrev is not standard C. See [`string.h`](http://pubs.opengroup.org/onlinepubs/009695399/basedefs/string.h.html) at the Open Group. – Matthew Flaschen Dec 29 '10 at 04:29

sorry, i thought it was platform-irrelevant. – Lion Dec 29 '10 at 04:30

and sorry again for the wrong example. but does a file like "string.c" exist? – Lion Dec 29 '10 at 04:32

If you just want to see the source to an implementation of the standard C library (albeit one that is in wide use), the source to glibc is available. You can clone the git repository:
git clone git://sourceware.org/git/glibc.git
You can also examine the source in a browser. Here's the string library, for instance.
glibc does not include strrev(). However, if you Google for
strrev c
you'll get hits to various implementations. For example: http://www.cas.mcmaster.ca/~kahl/SE2S03/2006/C/strrev.c and ftp://ftp.ecs.vuw.ac.nz/pub/libs/libstrings/strrev.c.

It depends where your particular compiler puts it. Many compilers don't provide the library source code.

This is an obscure product that I haven't used. How do you know this package includes library source? – Jonathan Wood Dec 29 '10 at 04:32

no. it doesn't provide source code files. instead lots of *.lib files are included. – Lion Dec 29 '10 at 04:39
