[Seobeo] Linux epoll. Set the client socket to be nonblocking so that it doesn't stop loading when two different threads handle different client calls. I might have problem with socket not being cleaned up properly so need to check that.

#include "dowa.h"

char *Dowa_Int32ToString(uint32 int32, char *buffer)
{
  sprintf(buffer, "%d", int32);
  return buffer;
}
