var OpenFile = os.OpenFile

OpenFile is the generalized open call; most users will use Open or Create instead. It opens the named file with specified flag (O_RDONLY etc.) and perm (before umask), if applicable. If successful, methods on the returned File can be used for I/O. If there is an error, it will be of type *PathError.

Under both Unix and Windows this will allow open files to be renamed and or deleted.

Functions

func Create

func Create(name string) (*os.File, error)

Create creates the named file with mode 0666 (before umask), truncating it if it already exists. If successful, methods on the returned File can be used for I/O; the associated file descriptor has mode O_RDWR. If there is an error, it will be of type *PathError.

func FindUnusedDriveLetter added in v1.55.0

func FindUnusedDriveLetter() (driveLetter uint8)

FindUnusedDriveLetter does nothing except on Windows.

func IsReserved added in v1.56.0

func IsReserved(path string) error

IsReserved checks if path contains a reserved name

func MkdirAll added in v1.56.0

func MkdirAll(path string, perm os.FileMode) error

MkdirAll just calls os.MkdirAll on non-Windows.

func Open

func Open(name string) (*os.File, error)

Open opens the named file for reading. If successful, methods on the returned file can be used for reading; the associated file descriptor has mode O_RDONLY. If there is an error, it will be of type *PathError.

func PreAllocate added in v1.50.20

func PreAllocate(size int64, out *os.File) (err error)

PreAllocate the file for performance reasons

func SetSparse added in v1.50.20
