What if the Result is -9 in MakeDir(arg)

[Lou Eichner]

MakeDir ("C:\\DATA");
assume the directory DATA exists.

Using the function MakeDir works great. It assumes that the directory does
not exist. If the directory does exist, the return is -9. There is a break
from the program. How do you get around this break and stay in the program
?

I assume this happens only in debugging mode.
This probably means you have "break on library errors" checked in the options-menu.
Uncheck it and the debugger won't break.

Good luck,

Hello, Lui.

You can use something like this code:

int oldBreakState, result;

oldBreakState = SetBreakOnLibraryErrors (0); // disables break on
error
result = MakeDir ("C:\\DATA");
SetBreakOnLibraryErrors (oldBreakState); // restores the old
'break' state
if (result != 0)
{
// process errors
}

I know this is an old thread.  But I just want to reply in case someone is interested.

You may not want to create a new directory if it already exists.  Try this:

fileIsExisting = FileExists(buf, 0);  // buf is the directory you want to create
if (!fileIsExisting)               
   MakeDir (buf);
