I agree, we should change Curl_write() accordingly. Your patch could be
committed with the const, and then we (I?) can go on to fix the existing code.

Two things:

#1 - These functions never return anything that hint the caller of them that
      they return since they would otherwise block. It will force applications
      to guess when they should just wait for the socket to become ready, or
      when to bail out.

#2 - Less important: it doesn't use the standard 2 space indent levels, and it
      has a few lines > 80 columns.
