Hello ..
sorry, i guess i just made a mistake in the copy and paste ... here are the
detials of the data structures :
typedef struct {
UInt orderID ;
ULong timeStmp ; // stored as seconds
CharPtr name ;
CharPtr address;
UInt totalQuantity ;
int expMonth;
int expYear;
} CustomerType ;
typedef CustomerType *CustomerPtr ;
typedef struct {
UInt orderID ;
ULong timeStmp ; // stored as seconds
UInt totalQuantity ;
int expMonth;
int expYear;
Char custData ;
} PackedCustomerType ;
typedef PackedCustomerType * PackedCustomerPtr ;
code snippet :
CustomerPtr src ;
PackedCustomerPtr dest, nilP = 0;
custHandle = DmNewHandle(size);
dest = (PackedCustomerPtr) DmHandleLock(custHandle) ;
err = DmWrite(dest, (ULong)&nilP->orderID, &src->orderID ,
sizeof(src->orderID));
ErrFatalDisplayIf(err, "Couldnot pack record");
err = DmWrite(dest, (ULong)&nilP->timeStmp, &src->timeStmp,
sizeof(src->timeStmp));
ErrFatalDisplayIf(err, "Couldnot pack record");
err = DmWrite(dest, (ULong)&nilP->totalQuantity, &src->totalQuantity,
sizeof(src->totalQuantity)) ;
ErrFatalDisplayIf(err, "Couldnot pack record");
err = DmWrite(dest, (ULong)&nilP->expMonth, &src->expMonth,
sizeof(src->expMonth)) ;
ErrFatalDisplayIf(err, "Couldnot pack record");
problem : the last DmWrite() gived a dmErrNotValidRecord message.
