CGL

CGL - A CGI Library in ANSI C

Features

Written in ANSI C.
Clean interface.
Should run on all Unixes; used on Open/Free/NetBSD, Solaris 2.5.1+, Tru64 4.0D+, Linux, and once I believe, on AIX.
Default data limits for safety; but all are run-time configurable. No hard limits on number of name-value pairs, or the sizes of either.
Data structures can be used for other things such as hashed indexes (for an associative array-like behaviour).
Some additional functions (like string growing) to make CGI writing in C easier.
