To add content to packet payload you can use following commands: std::ostringstream msg; msg << “Hello World!” << ‘\0’; Ptr<Packet> packet = Create<Packet> ((uint8_t*) msg.str().c_str(), msg.str().length()); To read content from packet payload: uint8_t *buffer = new uint8_t[packet->GetSize ()]; packet->CopyData(buffer, packet->GetSize ()); std::string s = std::string((char*)buffer);
int pcntl_fork ( void ) int pcntl_waitpid ( int pid, int &status, int options) int pcntl_wexitstatus ( int status) We already discussed the problems inherent to using a singe process for a PHP script – multi-processor boxes are under-utilised, and single-processor boxes are often left waiting for slow operations to complete before they can continue […]
