Description
TMarshal is a class that facilitates working with memory buffers.
TMarshal is a low-level API for marshalling arguments. It copies data in and out of buffers without dealing directly with pointers.
TMarshal introduces many functions and procedures to:
- Write a number of bytes into blocks of memory referenced by wrapped pointers.
- Read a number of bytes from blocks of memory referenced by wrapped pointers.
- Allocate memory of a certain size and return it as a wrapped pointer.
- Free memory referenced by a wrapped pointer.
