Try this:

if (!*dbP)
{

if (err==dmErrCantFind)
err = DmCreateDatabase(cardNo, name, creator, type, false);
if (err != errNone)
return err;
*created = true;
*dbP = DmOpenDatabaseByTypeCreator(type, creator, mode);
if (! *dbP)
return DmGetLastErr();
}
return err;
}
What is happing is that you are using OpenOrCreateDB before it is actually
being defined and the compiler doesn't know what it will return or its
parameters, so it assumes that they are "int" by default. Once you define
the function and it does not return as "int" the compiler complains.
I would actually put "extern Err OpenOrCreateDB(DmOpenRef *dbP, UInt32 type,
UInt32 creator, UInt16 mode, UInt16 cardNo, char* name, Boolean* created);"
in a header file included at the top of the source file that uses that
function.

I call the function. CodeWarrior informs me:

PROVIDING A GREAT FAVOR. I HAVE PROBABLY FAILED TO PROPERLY DEFINE A
