public 
  procedure WriteBuffer(const Buffer; Count: LongInt);
  procedure WriteBuffer(const Buffer: TBytes; Count: NativeInt);  Overload;
  procedure WriteBuffer(const Buffer: TBytes; Offset: NativeInt; 
                       Count: NativeInt);  Overload;

Description

WriteBuffer writes Count bytes to the stream from Buffer. If the stream does not allow Count bytes to be written, then an exception is raised.

WriteBuffer should be used to write a fixed number of bytes, such as when writing structures or the content of variables. If the number of bytes is not determined, use TStream.Write instead. WriteBuffer uses Write internally to do the actual writing.

Errors

If the stream does not allow to write Count bytes, then an exception is raised.
