GetMemPtr
Reads a pointer-sized value from a memory address into a LongPtr variable.
Syntax: GetMemPtr Address , retVal
- Address
- required LongPtr. The address to read from.
- retVal
- required LongPtr. The variable to receive the pointer-sized value read from Address.
The number of bytes read matches the host's pointer width --- four bytes in 32-bit builds, eight bytes in 64-bit builds. The bytes are interpreted in the host's native byte order. The address is read directly with no bounds or alignment check.
Example
vb
' Read the IUnknown vtable pointer of a Collection instance.
Dim c As Collection = New Collection
Dim vtbl As LongPtr
GetMemPtr ObjPtr(c), vtbl
Debug.Print "vtable at "; Hex(vtbl)
