Re: Close apache console from XP/2003/Vista

Sucess!

I ended up not going down the GenerateConsoleEvent but your suggestion 

inspired me to do some digging. I read on the win32 api help a while 

that GenerateConsoleEvent will basically just call the registered the 

even handler, so I searched through the source code to see if I could 

find it, and yup found it. Then followed a bit of code and realised 

something, apache creates events to signal different things.

Here is a little helper function I wrote so other people can benefit 

from what I have found (signal is "shutdown" or "restart")

bool SendApacheSignal(DWORD pid, char *signal)
{
  char buff[128];
  HANDLE event = NULL;
  if (sprintf(buff, "ap%d_%s", pid, signal))
  {
    event = ::OpenEvent(EVENT_MODIFY_STATE, false, buff);
  }
  return event && ::SetEvent(event);
}

This is basically what httpd -k stop does on Win 9x but not XP

Hope some of you find that useful and thanks for the inspiration Eric,
Matt

Thanks for this, I had tried the GenerateConsoleEvent api before without 

success, although reading that page the author is creating a remote 

thread to call the api from within the Apache process rather than 

externally so I'll play around with that.

Thanks,
Matt

My question is this: how can I gracefully close apache? The docs say 

to use

"httpd -k stop" but on our target platforms this always tries to stop 

the

service but we are actually running as a console. There is mention of 

using

kill on unix but I cannot find a suitable windows equivilant.

I've used e a little windows utility, SendSignal.exe, to send
cntrl-break to a similar a program in some automation.

Unfortunately it didn't look like any of the sysinsternals tools would
do it, but I may have just missed it.
