Hi,

If I use findfirst() in a directory containing only one subdirectory,
and no other files, then it returns 22 and sets errno to 22 (which is
ENOENT). If the directory contains more than one subdirectory, this does
not appear to be a problem.

Here is some sample code:
- ------------------------------------------------------------------------
#include <iostream>
#include <dir.h>
#include <dirent.h>
#include <string>

extern int errno;

int main()
{
    ffblk B;
    string s;
    cout << "where? ";
    cin >> s;

    int i = findfirst(s.c_str(), &B, FA_DIREC);
    cout << "return value " << i << "; errno " << errno << endl;
    return 0;
}
- ------------------------------------------------------------------------

Create a subdir, say c:\a
Then create c:\a\b

Now run this and type "c:\a\*" (excluding quotes).
I get "return value 22; errno 22"

Then create c:\a\c

Now run this and type "c:\a\*" (ex. quotes)
I get "return value 0; errno 0"

Am I doing something wrong, or is this a bug in the findfirst
implementation?

Bye for now,
