Package os implements a subset of the Go "os" package. See https://godoc.org/os for details.

Note that the current implementation is blocking. This limitation should be removed in a future version.

var (
	Stdin  = &File{0, "/dev/stdin"}
	Stdout = &File{1, "/dev/stdout"}
	Stderr = &File{2, "/dev/stderr"}
)

Stdin, Stdout, and Stderr are open Files pointing to the standard input, standard output, and standard error file descriptors.

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

File represents an open file descriptor.

func NewFile(fd uintptr, name string) *File

NewFile returns a new File with the given file descriptor and name.

func (f *File) Close() error

Close closes the File, rendering it unusable for I/O.

func (f *File) Fd() uintptr

Fd returns the integer Unix file descriptor referencing the open file. The file descriptor is valid only until f.Close is called.

func (f *File) Read(b []byte) (n int, err error)

Read reads up to len(b) bytes from the File. It returns the number of bytes read and any error encountered. At end of file, Read returns 0, io.EOF.

func (f *File) Write(b []byte) (n int, err error)

Write writes len(b) bytes to the File. It returns the number of bytes written and an error, if any. Write returns a non-nil error when n != len(b).
