NAME
udev_monitor_receive_device, udev_monitor_enable_receiving,
udev_monitor_set_receive_buffer_size, udev_monitor_get_fd,
udev_monitor_get_udev - Query and modify device monitor
SYNOPSIS
#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
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.
