Description
Méthodes responsables de l'écriture, dans le tampon de l'objet écrivain interne, de jusqu'à Count octets transmis dans le paramètre Buffer typé.
WriteVar tente d'écrire jusqu'à Count octets. WriteVar écrit octet par octet SizeOf(Buffer) octets transmis dans le paramètre Buffer typé. Si Count > SizeOf(Buffer), WriteVar écrit les octets dépassant SizeOf(Buffer) sous la forme d'octets $00.
WriteVar avance la position en cours dans le tampon interne sur le nombre d'octets Count.
