FS_ChangeOwner

function

Library: File system utilities (OMFSYS legacy)
Include: omfsys.xin

Declaration

define external function FS_ChangeOwner
                value      stream  path
   owner        value      integer owner
   group        value      integer group
   status       modifiable stream  statusvalue

Purpose

The omfsys library has been deprecated and will be removed from a future version of the language. Use omvfs instead.

This function allows you to change the ownership ID of a file or directory.

Input arguments:

"path" -- the name of the file
"owner" -- the new owner ID of the file
"group" -- the new group ID of the file

Output argument:

"statusvalue". This argument will contain either a zero length string if the function succeeds, or one of the following error codes:
- "EACCES" -- no search permission on a component of the path name
- "EINTR" -- a signal was caught during the function execution
- "EIO" -- a file system I/O error occurred
- "ELOOP" -- (UNIX only) link recursion was detected
- "ENAMETOOLONG" -- the path name exceeds the system limits
- "ENOENT" -- the specified path does not exist
- "ENOLINK" -- (UNIX only) a required link to a remote machine is inactive
- "ENOTDIR" -- the path name is not a valid directory
- "EMULTIHOP" -- (UNIX only) remote machine access is required but not allowed
- "EPERM" -- the user does not have the required permissions
- "EROFS" -- the file resides on a read-only file system
- "EINVAL" -- "group" or "owner" is out of range

Note that "newpath" must refer to a valid path name. Also, the user ID of the process must be the same as the file owner or the process must belong to the super-user.
