示例1: rename
func rename(oldname, newname string) error {
dirname := oldname[:lastIndex(oldname, '/')+1]
if hasPrefix(newname, dirname) {
newname = newname[len(dirname):]
} else {
return &LinkError{"rename", oldname, newname, ErrInvalid}
}
// If newname still contains slashes after removing the oldname
// prefix, the rename is cross-directory and must be rejected.
// This case is caught by d.Marshal below.
var d syscall.Dir
d.Null()
d.Name = newname
buf := make([]byte, syscall.STATFIXLEN+len(d.Name))
n, err := d.Marshal(buf[:])
if err != nil {
return &LinkError{"rename", oldname, newname, err}
}
if err = syscall.Wstat(oldname, buf[:n]); err != nil {
return &LinkError{"rename", oldname, newname, err}
}
return nil
}示例2: Rename
// Rename renames a file.
func Rename(oldname, newname string) error {
var d syscall.Dir
d.Null()
d.Name = newname
buf := make([]byte, syscall.STATFIXLEN+len(d.Name))

return &PathError{"rename", oldname, err}
}
if err = syscall.Wstat(oldname, buf[:n]); err != nil {
