cgiwrap_getenv(3)
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.
