Pointer
DIM Var AS Pointer
This native datatype represents a pointer, i.e. an address in memory.
This is an absolute synonymous of the
Integer datatype on 32 bits systems.
In the 64-bits version of
Gambas, a Pointer is a synonymous for the
Long datatype.
Example
This example puts the (hex) representation of a
Single number into a f. See
Single Precision
DIM i AS Integer ' 4 bytes
DIM f AS Single ' 4 bytes
DIM hH AS Pointer ' Needs to be allocated
i = &h3EAAAAAA& 'IEEE representation of 1/3
hH = Alloc(4)
WRITE #hH, i
READ #hH, f
Free(hH)
