hi

I'm using one popen function, via that i'm executing the unix commands. The Popen function is failling when it get called on 251 st time. Here is the code.

FILE *in=NULL;
in=popen("ls -l | wc -l", "r");
if(in == NULL)
{
cout<<" ERROR IN GETTING DIR LIST1 "<<endl;
exit(0) ;
}
else
cout<<"Success "<<endl;
