示例1: Chmod
// Chmod changes the mode of the file to mode.
// If there is an error, it will be of type *PathError.
func (f *File) Chmod(mode FileMode) error {
if err := f.checkValid("chmod"); err != nil {
return err
}
if e := syscall.Fchmod(f.fd, syscallMode(mode)); e != nil {
return &PathError{"chmod", f.name, e}
}
return nil
}示例2: Chmod
// Chmod changes the mode of the file to mode.
// If there is an error, it will be of type *PathError.
func (f *File) Chmod(mode FileMode) error {
if f == nil {
return ErrInvalid
}
if e := syscall.Fchmod(f.fd, syscallMode(mode)); e != nil {

}示例3: Chmod
func (f *file) Chmod(mode uint32) fuse.Status {
f.fdLock.RLock()
defer f.fdLock.RUnlock()
// os.File.Chmod goes through the "syscallMode" translation function that messes
// up the suid and sgid bits. So use syscall.Fchmod directly.
err := syscall.Fchmod(f.intFd(), mode)
return fuse.ToStatus(err)
}示例4: Chmod
// Chmod changes the mode of the file to mode.
func (f *File) Chmod(mode int) Error {
if e := syscall.Fchmod(f.fd, mode); e != 0 {
return &PathError{"chmod", f.name, Errno(e)}
