Modify filters

Part of [udev\_monitor\_filter\_update(3)](/udev_monitor_filter_update/3.md).

## NAME

udev\_monitor\_filter\_update, udev\_monitor\_filter\_remove, udev\_monitor\_filter\_add\_match\_subsystem\_devtype, udev\_monitor\_filter\_add\_match\_tag - Modify filters

## 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.
