// Receive a binary encoded 'picture' message from the socket (or actor).
// This method is similar to zsock_recv, except the arguments are encoded
// in a binary format that is compatible with zproto, and is designed to
// reduce memory allocations. The pattern argument is a string that defines
// the type of each argument. See zsock_bsend for the supported argument
// types. All arguments must be pointers; this call sets them to point to
// values held on a per-socket basis.
// Note that zsock_brecv creates the returned objects, and the caller must
// destroy them when finished with them. The supplied pointers do not need
// to be initialized. Returns 0 if successful, or -1 if it failed to read
// a message.
