C++ (Cpp) refcnt Exemples

Exemple #1

Fichier : msg.cpp Projet : neon77/libzmq

void zmq::msg_t::add_refs (int refs_)
{
    zmq_assert (refs_ >= 0);

    //  Operation not supported for messages with metadata.
    zmq_assert (u.base.metadata == NULL);

    //  No copies required.
    if (!refs_)
        return;

    //  VSMs, CMSGS and delimiters can be copied straight away. The only
    //  message type that needs special care are long messages.
    if (u.base.type == type_lmsg || is_zcmsg() ) {
        if (u.base.flags & msg_t::shared)
            refcnt()->add (refs_);
        else {
            refcnt()->set (refs_ + 1);
            u.base.flags |= msg_t::shared;
        }
