cgiwrap_getenv3

Usage

Arguments

k - the environment variable to lookup

Overview

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.
