var UnixDirentMaxSize = int(unsafe.Sizeof(unix.Dirent{}))

UnixDirentMaxSize is the maximum size of unix.Dirent in bytes.

Functions

func ParseDirents

func ParseDirents(buf []byte, handleDirent func(ino uint64, off int64, ftype uint8, name string, reclen uint16) bool)

ParseDirents parses dirents from buf. buf must have been populated by getdents64(2) syscall. It calls the handleDirent callback for each dirent.

func RenameAt

func RenameAt(oldDirFD int, oldName string, newDirFD int, newName string) error

RenameAt is a convenience wrapper to make the renameat(2) syscall. It additionally handles empty names.

func StatAt

func StatAt(dirFd int, name string) (unix.Stat_t, error)

StatAt is a convenience wrapper around newfstatat(2).

func Utimensat

func Utimensat(dirFd int, name string, times [2]unix.Timespec, flags int) error

Utimensat is a convenience wrapper to make the utimensat(2) syscall. It additionally handles empty name.
