SYNOPSIS         top

       #include <libudev.h>

       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);

       int udev_monitor_get_fd(struct udev_monitor *udev_monitor);

       struct udev
                                          *udev_monitor_get_udev(struct udev_monitor *udev_monitor);

RETURN VALUE         top

       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.
