LongPtr data type
LongPtr (Long integer on 32-bit systems, LongLong integer on 64-bit systems) variables are stored as:
Signed 32-bit (4-byte) numbers ranging in value from -2,147,483,648 to 2,147,483,647 on 32-bit systems
Signed 64-bit (8-byte) numbers ranging in value from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 on 64-bit systems
Note
LongPtr is not a true data type because it transforms to a Long in 32-bit environments, or a LongLong in 64-bit environments. Using LongPtr enables writing portable code that can run in both 32-bit and 64-bit environments. Use LongPtr for pointers and handles.
