digitalmars.D - catching access violations of external programs

Is there any way to catch access violations of external programs?

#
# int ret = system("runMe arg1 arg2");
#

The code above returns a defined value if runMe segfaults in a Unix
environment.

This doesn't work under Windows as it produces a pop up notifying the
user of the access violation. Is there any way to disable those pop ups
and guarantee a return to the calling program?

I guess you'll have to call Windows API's like CreateProcess instead of
using std.c.process.system directly.

I usually try to minimize the use of platform dependent functions...

Thanks,
