Re: [lwip-commits] [SCM] lwIP - A Lightweight TCPIP stack branch, master, updated. master_at_STABLE-2_0_0-238-g9e0b367

It's a function:
http://pubs.opengroup.org/onlinepubs/009604499/functions/index.html

And 'index' always potentially shadows a global. However, it's not a problem unless you include that header file and compile it as plain old C. Hard to find...

Good catch on the missing “int” parameter!  Just curious, where is the global variable named “index”?  Also there are a lot of other uses of local variables named “index” in LwIP code.  Do these also have a shadowing problem?
