I have partially wrapped it for Judith's IDE.
Take a look at process.ew in IDE package.
I launch process with this function: CreateProcessHi ()
I check if process
which was launched is still alive with this code:
if(GetExitCodeProcess(hNewProcess)!=STILL_ACTIVE) then
I have tip for you:
The easiest way to know if someone has already wrapped some function is to
search in your Euphoria programs downloads directory for function name, in your
case "CreateProcess". Ofcourse you have to first download almost all contributed
programs.
My directory with downloaded Euphoria programs is 250 MB large.

Subject: Wrapping "CreateProcess"
Hi everyone,
I am trying to wrap the Win32 "CreateProcess" function. I want to launch
an application from Eu and get the application's process handle via
"CreateProcess". I then want to pass the handle to the Win32
"WaitForInputIdle" function in order to suspend my main process
until the child process is ready.
So far, my wrapped function doesn't work.
Has anyone already wrapped these and used them successfully.
Is there another way I can do this?
Thanks
Mark
