You should even be able to do like this (without a callback):
int main (int argc, char **argv) {
WServer server(argc, argv, WTHTTP_CONFIGURATION);
if (server.start()) {
WServer::waitForShutdown();
server.stop();
}
return 0;
}
But later you will have a dynamic application, so your solution might then
be better.
WRun(), or server.start(), starts the httpd server. The createApplication()
callback
is used only for the dynamic sessions -- for each session there's a call to
this callback
function.

Yes.

There is, see above. WRun() simply instantiates a server, configures and
starts it.
