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. .SH "RETURN VALUE" v - a newly allocated copy of the value of that variable, or .br NULL if not found. .SH "SEE ALSO" .BR cgiwrap_iterenv "(3), "cgiwrap_putenv "(3), "cgiwrap_init_emu "(3), "cgiwrap_writef "(3), "cgiwrap_init_std "(3), "cgiwrap_writevf "(3), "cgiwrap_read "(3), "cgiwrap_write "(3), "cgiwrap_getenv
