TIdBaseStream.Write Method (array of Byte, Longint, Longint)

Implements write operations using the platform-specific stream implementation.

Pascal

function Write(
    const ABuffer: array of Byte; 
    AOffset: Longint; 
    ACount: Longint
): Longint; override;

Parameters

Parameters	Description
Buffer	Values to be written to the stream.
Offset	Inital buffer position to be written to the stream.
Count	Number of byte values to be written to the stream.

Returns

Longint - Number of bytes written in the write operation.

Description

Write is an overridden method that isolates the platform-specific stream methods required to implement write operations. Write relies on the method implementation in a descendant classes for the protected virtual abstract IdWrite method.

On the .Net platform, Write uses an array of Byte to represent the Buffer containing values written to the stream.

On all other platforms, Write uses an untyped pointer to represent the Buffer containing values written to the stream. Write calls the Move procedure from the Runtime library to update the stream Buffer with the output values.

Use Read to input values using a platform-specific stream implementation.

Use Seek to reposition a platform-specific stream implementation.
