i have develop messaging app , came across sinch messaging sdk. had downloaded ios sdk , tried sinch instant messaging sample app. able send messages , messages. need know: can conversation list using sinch sdk latest message each conversation show in list? how can differentiate incoming chat messages different users. in sample see 1 chat messages screen populates messages different users. so, have property in sinch sdk differentiates conversations? is there possibility create group name, group image group chat? , how sinch api possibly maintain these group chat , single chat message? no, think of delivery mechanism messages, not mailbox. look @ senderid in messages, differentiate sending. you can implement feature sendmessagewithheaders , sinch im not channel discussion group, more suited multirecipient messages.

int value = 3; int *pvalue1 = &value; int *pvalue2(pvalue1); cout << (*pvalue1) << " " << (*pvalue2); in above code if have noticed have written int *pvalue2(pvalue1); instead of int *pvalue2 = new int; pvalue2 = pvalue1; still working , giving proper result. can 1 explain me of default function or constructor getting called in case? int *pvalue2(pvalue1); is equivalent to int* pvalue2 = pvalue1; just assign pvalue2 pvalue1 (assign pvalue2 address of variable value ).

#define define_stat(stat) \ struct fthreadsafestaticstat<fstat_##stat> statptr_##stat; the above line take unreal 4, , know ask on over unreal forums, think general c++ question warrants being asked here. i understand first line defines macro, not versed in preprocessor shenanigans in c++ , i'm lost on there. logic tells me backslash means declaration continues onto next line. fthreadsafestaticstat looks bit template, there's #'s going on in there , syntax i've never seen before in c++ could tell me means? understand may not have access unreal 4, it's syntax don't understand. ## preprocessor operator concatenation. so if use define_stat(foo) anywhere in code, gets replaced with struct fthreadsafestaticstat<fstat_foo> statptr_foo; before code compiled. here example a blog post of mine explain further. #include <stdio.h> #define decode(s,t,u,m,p,e,d) m ## s ## u ## t #define begin decode(a,n,i,m,a,t,e) int b...
