The FAQ has this entry, but it's marked "not yet updated for the
latest net release". I suspect it still applies. Can I remove the
warning?
A. How does wildcarding (globbing) work?
Q. If an application using CYGWIN.DLL starts up, and can't find the
PID environment variable, it assumes that it has been started from
the a DOS style command prompt. This is pretty safe, since the
rest of the tools (including bash) set PID so that a new process
knows what PID it has when it starts up.
If the DLL thinks it has come from a DOS style prompt, it runs a
`globber' over the arguments provided on the command line. This
means that if you type LS *.EXE from DOS, it will do what you
might expect.
Beware: globbing uses malloc. If your application defines malloc,
that will get used. This may do horrible things to you.
Thanks,
David
