{
UInt32 size;
Char str[32];
UInt16 card;
LocalID dbID;
Coord x, y;
x = 10;
y = 20;
card = ...;
dbID = ...; // you should have this code somewhere
DmDatabaseSize(card, dbID, NULL, &size, NULL);
StrIToA(str, size);
WinDrawChars(str, StrLen(str), x, y);
}
DmDatabaseSize() has ULongPtr's (UInt32 * in new SDK) which basically
allow you as a developer to pass a pointer to a specific data type and
have the function write to it.. its also known as passing by reference.
check out any good C/C++ programming book - it'll tell you more about
this type of programming :))
