NAME        top

       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        top

#include <libudev.h>struct udev_device*udev_monitor_receive_device(struct udev_monitor *udev_monitor);intudev_monitor_enable_receiving(struct udev_monitor *udev_monitor);intudev_monitor_set_receive_buffer_size(struct udev_monitor *udev_monitor,intsize);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,NULLis returned.       On success,udev_monitor_enable_receiving()andudev_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.

HISTORY        top

udev_monitor_receive_device(),udev_monitor_enable_receiving(),udev_monitor_set_receive_buffer_size(),udev_monitor_get_fd(), andudev_monitor_get_udev()were added in version 221.
