NAME
cgiwrap_getenv - the wrapper for getenv
SYNOPSIS
.Ss
#include <cgi/cgiwrap.h>
.Se
.Ss
NEOERR *cgiwrap_getenv (const char *k, char **v);
.Se
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.
