Functions

func DestroyMount

func DestroyMount(path string) error

func Dump(basePath string) interface{}

Dump prints out file system statistics

func Mounts

func Mounts() []mount.Point

func NewFileDescriptor

func NewFileDescriptor(fid FID, absPath string, flags int, mode os.FileMode) (*fileDescriptor, error)

Types

type Attr

type Attr struct {
	Ignore bool
	Pipe   bool
	FID    FID
}

Attr defines file descriptor inheritance rules for a new set of descriptors Ignore is unsupported. Pipe will create a new pipe and attach it to the child process. FID will inherit that descriptor in the child process.

type FID

type FID = common.FID

type FileDescriptors

type FileDescriptors struct {
	// contains filtered or unexported fields
}

func NewFileDescriptors

func NewFileDescriptors(parentPID common.PID, workingDirectory string, parentFiles *FileDescriptors, inheritFDs []Attr) (*FileDescriptors, func(wd string) error, error)
