// This is a stable class, and may not change except for emergencies. It
// is provided in stable builds.
// This class has draft methods, which may change over time. They are not
// in stable releases, by default. Use --enable-drafts to enable.

// and destroy when it has been sent.

zactor_send (zactor_t *self, zmsg_t **msg_p);
// Receive a zmsg message from the actor. Returns NULL if the actor
// was interrupted before the message could be received, or if there
// was a timeout on the actor.
// Caller owns return value and must destroy it when done.

// Probe the supplied object, and report if it looks like a zactor_t.
CZMQ_EXPORT bool
zactor_is (void *self);

// return the underlying libzmq actor handle; else if it looks like
// a libzmq actor handle, return the supplied value.

zactor_resolve (void *self);
// Return the actor's zsock handle. Use this when you absolutely need
// to work with the zsock instance rather than the actor.
