- NAME
- chown - change owner and group of a file
- SYNOPSIS
- int chown(const char *path, int owner, int group)
- DESCRIPTION
- The file that is named by path has its owner and group changed as
- specified. Only the super-user may change the owner of the file, because
- if users were able to give files away, they could defeat file-space
- accounting procedures. The owner of the file may change the group to a
- group of which he is a member.
- On some systems, chown clears the set-user-id and set-group-id bits on
- the file to prevent accidental creation of set-user-id and set-group-id
- programs.
- RETURN VALUE
- Zero is returned if the operation was successful; -1 is returned if an
- error occurs, with a more specific error code being placed in the global
- variable errno.
- ERRORS
- Chown will fail and the file will be unchanged if:
- [ENOTDIR] A component of the path prefix is not a directory.
- [ENAMETOOLONG] The path name exceeds PATH_MAX characters.
- [ENOENT] The named file does not exist.
- [EACCES] Search permission is denied for a component of the path
- prefix.
- [ELOOP] Too many symbolic links were encountered in translating
- the pathname. (Minix-vmd)
- [EPERM] The effective user ID is not the super-user.
- [EROFS] The named file resides on a read-only file system.
- [EFAULT] Path points outside the process's allocated address space.
- [EIO] An I/O error occurred while reading from or writing to the
- file system.
