Types

type Info

type Info struct {
	// ID is a unique identifier of the mount (may be reused after umount).
	ID int

	// Parent indicates the ID of the mount parent (or of self for the top of the
	// mount tree).
	Parent int

	// Major indicates one half of the device ID which identifies the device class.
	Major int

	// Minor indicates one half of the device ID which identifies a specific
	// instance of device.
	Minor int

	// Root of the mount within the filesystem.
	Root string

	// Mountpoint indicates the mount point relative to the process's root.
	Mountpoint string

	// Opts represents mount-specific options.
	Opts string

	// Optional represents optional fields.
	Optional string

	// Fstype indicates the type of filesystem, such as EXT3.
	Fstype string

	// Source indicates filesystem specific information or "none".
	Source string

	// VfsOpts represents per super block options.
	VfsOpts string
}

Info reveals information about a particular mounted filesystem. This struct is populated from the content in the /proc/<pid>/mountinfo file.

func GetMounts

func GetMounts() ([]*Info, error)

GetMounts retrieves a list of mounts for the current running process.

func PidMountInfo

func PidMountInfo(pid int) ([]*Info, error)

PidMountInfo collects the mounts for a specific process ID. If the process ID is unknown, it is better to use `GetMounts` which will inspect "/proc/self/mountinfo" instead.
