Using ZMQ 4.0.4 on windows 64bit in Visual studio with a simple REQ-REP
with multipart messages.
All examples and guide show code like
int64_t more;
size_t more_size = sizeof more;
do {
/* Create an empty ØMQ message to hold the message part */
zmq_msg_t part;
int rc = zmq_msg_init (&part);
assert (rc == 0);
/* Block until a message is available to be received from socket */
rc = zmq_msg_recv (&part, socket, 0);
assert (rc != -1);
/* Determine if more message parts are to follow */
rc = zmq_getsockopt (socket, ZMQ_RCVMORE, &more, &more_size);
assert (rc == 0);
zmq_msg_close (&part); } while (more);
I found that the value of more is a ridiculously large negative integer
and fails to detect the last frame unless I initialize it to zero.
(note Debug in GCC zeros memory, Visual Studio does not.)
Inspection of the value in hex may reveal a 64 bit porting problem,
The values is 0xCCCCCCCC00000000
Which is setting it to a int const without the ull specifier ????
Anyway I change "int64_t more;" to "int64_t more = 0;" and operation
is restored.
