NAME

       rfio_chown - change owner and group of a directory/file

SYNOPSIS

       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_chown (const char *path, uid_t new_uid, gid_t new_gid)

DESCRIPTION

       rfio_chown  sets  the  owner and the group of a directory/file to the numeric values in owner and group respectively.  If owner or group is
       specified as -1, rfio_chown() does not change the corresponding ID of the file.

       path   specifies the logical pathname relative to the current directory or the full pathname.

       The effective user ID of the process must match the owner of the file or be super-user.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       EPERM	    The effective user ID does not match the owner of the file and is not super-user.
