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.
