cgireadstate() - read state variables

SYNOPSIS

#include "cgi.h"

int cgireadstate(cp)
CGI *cp;

DESCRIPTION
The cgireadstate() function is an internal API function that parses the state cookie for state variables, reading the state file if needed. It returns the status: 1 if success and 0 if error (no state cookie, no file, etc.).

This function never needs to be called by the user; the state is automagically read when needed. It can be used to explicitly get the status of the state parse/read operation if desired.
