## Description

Routines for managing mounted UNIX mount points and paths.

Note that `<gio/gunixmounts.h>` belongs to the UNIX-specific GIO interfaces, thus you have to use the `gio-unix-2.0.pc` pkg-config file when using it.

Emitted when the unix mounts have changed.

`monitor` : | the object on which the signal is emitted
`user_data` : | user data set when the signal handler was connected.
