Hello to everyone.

I'm making a CD player using TPW1.5. I use MCI message-based interface to
send commands. But I have a problem:
I always receive "general protection fault" errors when I run those
commands. The program is correct, because the compilation does not return
any errors. Even if it were incorrect, I should receive MCI error codes
returned by mciSendCommand function, but I do not receive such errors, but
"general protection faults", so run-time errors!!!!

Does anyone can help me? Looking at the examples of other people, I
implemented a "variable cleaning" at the beginning of each function, like
that:

var
  Info : TMCI_Open_Parms;

begin
  FillChar (Info, SizeOf (TMCI_Open_Parms), #0);
  [...]
end;

but the problem persists. Please help me, if you can! If you put my e-mail
address in the Cc: field of the reply (mauro...@tin.it), I'll be grateful.
Thank you!

In the example you gave, there are 3 pChar fields within the record,
that all get initialised to NIL in your routine. At least two of these
appear to be required parameters. And dereferencing a NIL pointer
gives you a GPF.

Hope this helps,
