NAME
       cgiwrap_getenv  - the wrapper for getenv

SYNOPSIS
       #include <cgi/cgiwrap.h>

       NEOERR *cgiwrap_getenv (const char *k, char **v);

ARGUMENTS
       k - the environment variable to lookup

DESCRIPTION
       cgiwrap_getenv  wraps  the  getenv  function  for access to environment
       variables, which are used to pass data to CGI  scripts.	 This  version
       differs	from the system getenv in that it makes a copy of the value it
       returns, which gets around  problems  when  wrapping  this  routine  in
       garbage	collected/reference  counted languages by moving the ownership
       of the data to the calling function.

RETURN VALUE
       v - a newly allocated copy of the value of that variable, or
       NULL if not found.
