CHOWN(2) Minix Programmer's Manual CHOWN(2)
|
||
|
||
|
||
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.
