NAME
cgiwrap_getenv - the wrapper for getenvSYNOPSIS
#include <cgi/cgiwrap.h>
NEOERR *cgiwrap_getenv (const char *k, char **v);
ARGUMENTS
k - the environment variable to lookupDESCRIPTION
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, orNULL if not found.
