wifi direct - How to find Wifip2p groups in android -


i'm trying use wifi-direct connecting multiple devices on wifi in master-slave style (one many)- 1 client creates group using "creategroup" function, , other clients should connect group (manually). when client press on "discover peers" button, want give him list of master peers. , here problem- can't find way differentiate between slave peers , master peer (the 1 initiate creategroup request).

is there way filter out slave peers , keep master peers?

you should discovering services rather peers, though api work better if peer discovery, here's proposal logic: slave:

  • start peerdiscovery
  • when peers changed event, start service discovery (for service_type defined master)
  • add discovered services selection list come (note come 1 one, , i've seen max 5 seconds between discovered services)

with master

  • creategroup
  • add local service advertise master
  • start peer discovery, , make sure monitoring discovery state changes stays on (if goes off, service advertisement not seen slaves)

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.
