SYNOPSIS

       #include <libudev.h>

       int udev_monitor_filter_update(struct udev_monitor *udev_monitor);

       int udev_monitor_filter_remove(struct udev_monitor *udev_monitor);

       int udev_monitor_filter_add_match_subsystem_devtype(struct udev_monitor *udev_monitor,
                                                           const char *subsystem,
                                                           const char *devtype);

       int udev_monitor_filter_add_match_tag(struct udev_monitor *udev_monitor, const char *tag);

RETURN VALUE

       On success, udev_monitor_filter_update(), udev_monitor_filter_remove(),
       udev_monitor_filter_add_match_subsystem_devtype() and udev_monitor_filter_add_match_tag()
       return an integer greater than, or equal to, 0. On failure, a negative error code is
       returned.
