cgiwrap_getenv(3) cgi/cgiwrap.h 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 vari- ables, 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 col- lected/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.
