Description
Methods responsible for writing up to Count bytes passed in the typed Buffer parameter into the internal writer object's buffer.
WriteVar attempts to write up to Count bytes. WriteVar writes byte-by-byte SizeOf(Buffer) bytes passed in the typed Buffer parameter. If Count > SizeOf(Buffer), then WriteVar writes bytes exceeded SizeOf(Buffer) as $00 bytes.
WriteVar advances the current position in the internal buffer onto the Count number of bytes.
