This question is more specific to libcURL, so you might want to ask in
libcURL's mailing-list. However looking at the documentation,
it seems that using strlen would be enough. So,

request.setOpt(new cURLpp::Options::PostFields("abcd"));
request.setOpt(new cURLpp::Options::PostFieldSize(4));

Would be alright.
