nfs, ftp, http, httpproxy, etc.) and f_device_get() (abstract method for calling aforementioned f_media_get_TYPE()). Previously, if $probe_only was present and non-NULL, the TYPE functions would check for $file and exit with an appropriate error status (success if the file exists and readable, failure otherwise). While this has been retained, a pair of globals has been introduced: $PROBE_EXIST and $PROBE_SIZE (see `/usr/share/bsdconfig/media/common.subr') The $PROBE_EXIST global can be used where you need the functionality of simply testing for existence (previously the _only_ functionality). Meanwhile, the new $PROBE_SIZE global can be used to cause the TYPE function to print the size of the file (in bytes) on standard-out (or -1) if not found or an error occurs. NOTE: If an error occurs, it is logged with the dprintf function, which is visible with `-d' flag or debug=1. In many cases, where you need to get the size of a file _and_ check for its existence, you can use the return status of a $PROBE_SIZE call. |
