Class: ISLDataBuffer

Syntax

Delphi:

function ByteWrite() : PByte;

C++ Builder:

PByte __fastcall ByteWrite();

Visual C++ (MFC):

ByteWrite();

Summary

Returns write pointer to the buffer data.

Description

This method is not guaranteed to preserve the current data in the buffer. If you need to read and write to the buffer, use the Modify method. Use this method when you need write access to the data for writing. If you just need to read the data, use Read instead! Read is faster, as Write may result in additional memory allocation operation if the internal data buffer is shared.

Example:

var RawData : Pointer;

RawData := SomeBuffer.ByteWrite();
