Please note that for 3.12 the defibition of RTN_SUCCESS was changed to:

#define RTN_SUCCESS(STATUS) ((STATUS)==0)

At one time we were thinking of letting the low order bit of status
meand success if 0 and failure if 1. This convention was never implemented
as the old definition containing && instead of & demonstrates.

The only convention is status=(0, not zero) meand (success, failure).

There is no reason to use RTN_SUCCESS. I just use

if(status) {/* this is error handling code*/}

or

if(!status) {/* This is code for success */ }
