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

and is not super-user.
