publish - ZMQ Pub/Sub returns ETERM -


i have 1 zmq_pub socket in 1 process, connected zmq_sub socket in process, it's server. thing need publish many messages can. i'm sure it's connected first.

i'm running load test, firing thousands of identical messages pub. @ other side, i'm polling zmq_sub socket, , receiving messages when needed.

the weird thing every 1000 messages received, zmq_poll returns eterm 3 times. can't figure out.

-- solution in comments bellow.

turns out misinterpreting return code of poll, recv , send functions. returns -1 everytime gets signal, , lot of eintr, that's fine, normal. can ignore them , repeat trying do. in polling, can continue. if came send or recv, can keep trying send or recv long errno == eintr. problem solved

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
