SYNOPSIS

11       #include <libudev.h>
12
13       struct udev_device
14                                                       *udev_monitor_receive_device(struct udev_monitor *udev_monitor);
15
16       int udev_monitor_enable_receiving(struct udev_monitor *udev_monitor);
17
18       int
19                                                udev_monitor_set_receive_buffer_size(struct udev_monitor *udev_monitor,
20                                                int size);
21
22       int udev_monitor_get_fd(struct udev_monitor *udev_monitor);
23
24       struct udev *udev_monitor_get_udev(struct udev_monitor *udev_monitor);
25

RETURN VALUE

27       On success, udev_monitor_receive_device() returns a pointer to a newly
28       referenced device that was received via the monitor. The caller is
29       responsible to drop this reference when done. On failure, NULL is
30       returned.
31
32       On success, udev_monitor_enable_receiving() and
33       udev_monitor_set_receive_buffer_size() return an integer greater than,
34       or equal to, 0. On failure, a negative error code is returned.
35
36       On success, udev_monitor_get_fd() returns the file descriptor used by
37       this monitor. On failure, a negative error code is returned.
38
39       udev_monitor_get_udev() always returns a pointer to the udev context
40       that this monitor is associated with.
