[zeromq-dev] rcvd msg does not match sent msg

[Ashok Chippa]

Hi,

I am trying to send a small msg from a thread to its main process using
inproc. I have tried
several types: REP-REQ, XREP-XREQ, ROUTER-DEALER, PUB-SUB, etc. without
success.
Here's what I get when using REP-REQ:
achippa at ubuntu:~/projects/groupchat$ ./client 10.1.1.1 1111
client started with ipaddress 10.1.1.1 port 1111
connected to user socket
C foo
test_create_group: packed size = 21
0*8*00*1*000 18002000 28003203 666f6f38
0040004a 00
main: rcvd msg size = 21
0*0*00*0*000 18002000 28003203 666f6f38
0040004a 00
gc_client_handle_message
message 'group_chat_msg': missing required field 'direction'
Segmentation fault

When I replace REP-REQ with XREP-XREQ I get this:

achippa at ubuntu:~/projects/groupchat$ ./client 10.1.1.1 1111
client started with ipaddress 10.1.1.1 port 1111
connected to user socket
C foo
test_create_group: packed size = 21
08001000 18002000 28003203 666f6f38
0040004a 00
main: rcvd msg size = 17
00ffffff8d1115 1f16ffffffe147 2affffff93ffffffd24a 1849ffffffbcffffffe3
22
gc_client_handle_message
data too short after length-prefix of 1222931
gc_client_handle_message: unpack returned NULL
client: gc_client.c:1020: main: Assertion `rc == 0' failed.
Aborted

More than reading about zmq, I need pointers from those who have more
experience with it. Any pointers to get around these, please?

Thanks,
Ashok
