cgiwrap_getenv: the wrapper for getenv

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.
