Returns the address of a variable or object
Syntax
Syntax
result = VarPtr ( lhs )
Parameters
lhs
A variable or object.
T
Any data type.
Return Value
Returns the address of a variable or object.
Description
This operator returns the address of its operand.
When the operand is of type
String, the address of the internal string descriptor is returned. Use
Operator Strptr (String Pointer) to retrieve the address of the string data.
The operand cannot be an array, but may be an array element. For example,
"VarPtr(myarray(0))" returns the address of
"myarray(0)".
Example
Dim a As Integer, addr As Integer
a = 10
'' place the address of a in addr
addr = CInt( VarPtr(a) )
'' change all 4 bytes (size of INTEGER) of a
Poke Integer, addr, -1000
Print a
'' place the address of a in addr (same as above)
addr = CInt( @a )
'' print the least or most significant byte, depending on the CPU endianess
Print Peek( addr )
