.SH "NAME" udev\_monitor\_new\_from\_netlink, udev\_monitor\_ref, udev\_monitor\_unref - Create, acquire and release a udev monitor object

.SH "SYNOPSIS"

```
#include <libudev.h>
```

.HP 1224u **struct udev\_monitor \*udev\_monitor\_new\_from\_netlink(struct udev \*udev, const char \*name);**

.HP 912u **struct udev\_monitor \*udev\_monitor\_ref(struct udev\_monitor \*udev\_monitor);**

.HP 960u **struct udev\_monitor \*udev\_monitor\_unref(struct udev\_monitor \*udev\_monitor);**

.SH "RETURN VALUE"

.PP On success, **udev\_monitor\_new\_from\_netlink()** returns a pointer to the allocated udev monitor. On failure, **NULL** is returned. **udev\_monitor\_ref()** returns the argument that it was passed, unmodified. **udev\_monitor\_unref()** always returns **NULL**.

.SH "HISTORY"

.PP **udev\_monitor\_new\_from\_netlink()**, **udev\_monitor\_ref()**, and **udev\_monitor\_unref()** were added in version 221.
