struct udev_device *udev_monitor_receive_device(struct udev_monitor *udev_monitor);

int udev_monitor_enable_receiving(struct udev_monitor *udev_monitor);

int udev_monitor_set_receive_buffer_size(struct udev_monitor *udev_monitor, int size);

On success, udev_monitor_receive_device() returns a pointer to a newly referenced device that was received via the monitor. The caller is responsible to drop this reference when done. On failure, NULL is returned.

On success, udev_monitor_enable_receiving() and udev_monitor_set_receive_buffer_size() return an integer greater than, or equal to, 0. On failure, a negative error code is returned.

On success, udev_monitor_get_fd() returns the file descriptor used by this monitor. On failure, a negative error code is returned.

udev_monitor_get_udev() always returns a pointer to the udev context that this monitor is associated with.
