    Format

      #include  <unistd.h>

      int lchown  (const char *file_path, uid_t file_owner, gid_t
                  file_group);

1  –  Arguments

 file_path

    The name of the file for which you want to change the owner and
    group IDs.

 file_owner

    The new user ID for the file.

 file_group

    The new group ID for the file.

2  –  Description

    The lchown function changes the owner and/or group of the
    specified file (file_path). If the file is a symbolic link, the
    owner of the symbolic link is modified (in contrast to chown
    which would modify the file that the symbolic link points to).

    See also symlink, unlink, readlink, realpath, and lstat.

    -1                 Indicates an error. errno is set to any errno
                       value returned by chown.
