cgiwrap_getenv(3) - Linux man page
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.
