Sorry for this big delay. Now I have tried a little bit different way, but still I have a problem:
1/ I have started with the example from tutorials and created some ‘server’ code. I run it from CINT and it works a similar way as ‘nc’ (tested with nc client), no visible problem.
2/ I have plugged this part into some testing TThread frame, and here it is (as simplified as I could):
#include <stdio.h>
#include "TSocket.h" //net thread
#include "TServerSocket.h"
#include "TMonitor.h"
#include "TThread.h" // CINT? // -lThread
#include <iostream>
#include <fstream>
using namespace std;
const int MAXTHREADS=10;
//---------------------------------this part works quite fine when run from CINT alone--
void net_server( void *arg )
{
int port=9999;
while( 1==1 ){
printf("%s\n" ,"entered main while loop in net_server");
TServerSocket *ss = new TServerSocket(port, kTRUE);
TMonitor *mon = new TMonitor;
mon->Add(ss);
TSocket *s0 = 0, *s1 = 0, *s2 = 0;
int wait=1; //EXTRA
while (1) {
TSocket *s;
do{ s = mon->Select( 1000 ); printf("%s",".\n" );}while( (int)s==-1 );
if (s->IsA() == TServerSocket::Class()) {
if (!s0) {
s0 = ((TServerSocket *)s)->Accept();
mon->Add(s0);
} else if (!s1) {
printf("I am in s1 :%s\n","" );
s1 = ((TServerSocket *)s)->Accept();
mon->Add(s1);
}
continue;
}//if IsA
char aaa[1000]; int get;
char newline='\n';
get=s->RecvRaw( aaa , 1000, kDontBlock);
printf("Client %d: get==%d: <%s>\n", s==s0 ? 0 : 1, get, aaa );
aaa[get]='\0';
printf("Client %d: get==%d: <%s>\n", s==s0 ? 0 : 1, get, aaa );
if (get==0){
mon->Remove(s);
s0=NULL; // one client is fine for me (i can do two), here I recycle the s0 socket
}// get==0
if (strstr(aaa,"kill")!=0){
printf("in a kill : active==%d\n", mon->GetActive() );
mon->Remove(s);// this is removed. others not
mon->Remove(ss); ss->Close();
printf("in a kill : active==%d\n", mon->GetActive() );
}
if (mon->GetActive() == 0) {
printf("No more active clients... stopping\n");
break;
}
}//while (1)
} // BIG WHILE 1==1
printf("%s","net_server stop \n");
return ;
}// .............................................................net_server end
// ------------------------------MAIN----------------------
void testbench(){
TThread *shspe_threads[MAXTHREADS];
shspe_threads[1] = new TThread( "my_server" , net_server, NULL );
if (shspe_threads[1]==NULL){ printf("exiting, thread 1 not running\n%s","");return ;}
shspe_threads[1]->Run();
}// .....................................................................testbench
3/ I do
root -n
.L testbench.C+
testbench()
and … a result - even without sending data from outside (‘nc’) - it crashes in a short time when I play with enter in cint…
I have observed that do-while loop (that with ->Select, I fprint ‘.’ there) stops sometimes after enter, sometimes starts again. I see some TTermInputHandler:

Any idea? Please…
