udev-device record accessors[procedure] udev-device?
Accessors for udev-device records.
Listing devices[procedure] (udev-list-devices)
Return a list of devices identified by udev, represented by udev-device records.
Monitoring[procedure] (udev-monitor-start dispatcher #!key (polling-interval 0.2))
Start the udev monitor thread. dispatcher is a one-argument procedure that is is given an udev-device record for each udev event.
This procedure creates an srfi-18 thread which polls udev in polling-interval seconds.[procedure] (udev-monitor-stop! monitor)
Stop the udev monitor thread.
(use udev) (define (mountable-device? dev) (and (equal? (udev-device-type dev) "partition") (equal? (udev-device-subsystem dev) "block"))) (define (dispatcher dev) (let ((node (udev-device-node dev)) (action (udev-device-action dev))) (when (mountable-device? dev) (cond ((equal? action "add") (print "Mounting " node)) ((equal? action "remove") (print "Unmounting " node)))))) (thread-join! (udev-monitor-start dispatcher))
Miscellaneous[procedure] (udev-device-parent-with-subsystem-devtype dev subsystem devtype)
Find the next parent device, with a matching subsystem and devtype value, and fill in information from the sys device and the udev database entry (from the original documentation).
dev is an udev-device record. subsystem and devtype are strings. Returns a udev-device record.[procedure] (make-udev-device node subsystem type action syspath sysname sysnum driver properties)
Create a udev-device record. This procedure is usually only useful for mocking udev devices.
