I am trying to call a function. It is passing a number of variables relevant
to calling a database. I define the function, per a text I have. I call the
function. CodeWarrior informs me:
Error : identifier 'OpenOrCreateDB(...)' redeclared
was declared as: 'int (...)'
now declared as: 'unsigned short (void **, unsigned long, unsigned long,
unsigned short, unsigned short, char *, unsigned char *)'
THE CALLING FUNCTION FOLLOWS (THE CALL IS MADE ONE LINE UP FROM LAST CODE LINE):
static Err AppStart(void)
{
UInt16 mode = dmModeReadWrite;
Err err = errNone;
TransStruct *c;
Boolean created;
Char* DBName = (Char*) MemPtrNew(15); // allocate 15 bytes
DBName = "Transformers";
//Find the Transformer Database. If it doesn't exist, create it.
OpenOrCreateDB(&gTransformer, 'DATA', '!!$g', mode, 0, DBName, &created);
return err;
}
THE FUNCTION THAT IS CALLED IS:
//NEW CODE!!!
//Open a database. If it doesn't exist, create it.
Err OpenOrCreateDB(DmOpenRef *dbP, UInt32 type, UInt32 creator, UInt16 mode,
UInt16 cardNo, char* name, Boolean* created)
{
Err err = errNone;
*created = false;
*dbP = DmOpenDatabaseByTypeCreator(type, creator, mode);
if (!*dbP)
{
err = DmGetLastErr();
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;
}
Have any data types or representations of data types that were legal a few
years ago when the code from which I am borrowing was written ceased to be
allowed? There are a series of additional messages after the error that begins
this post asserting that variable names are not defined.
undefined identifier 'created'
undefined identifier 'dbP'
undefined identifier 'cardNo'
I create the following as global variables:
/*********************************************************************
* Global variables
*********************************************************************/
typedef struct {
char FirstName[20];
char LastName[20];
char PhoneNum[20];
} TransStruct;
typedef TransStruct TransStructType;
typedef TransStruct* TransStructPtr;
DmOpenRef gTransformer;
ANYONE WHO CAN CLEAR THE BASIS FOR THIS ERROR SEQUENCE UP FOR ME WOULD BE
PROVIDING A GREAT FAVOR. I HAVE PROBABLY FAILED TO PROPERLY DEFINE A VARIABLE
TYPE, BUT SIMPLY DON'T SEE WHERE.
THANK YOU.
