Possible DIV3 bug? get_fileinfo appears not to work on Windows

Casper - 4-2-2018 at 03:04 PM

This is my test program:

Code:


COMPILER_OPTIONS _case_sensitive;

program test_get_fileinfo;
const
    path = "assets\";
    fileName = "test.dat";
global
    fileHandle;
    data = 777;
    result1;
begin
    fileHandle = fopen(path + fileName, "w");
    fwrite(offset data, sizeof(data), fileHandle);
    fclose(fileHandle);

    result1 = get_fileinfo(path + fileName);

    write_int(0, 20, 20, 0, &result1);

    repeat
        frame;
    until (scan_code != 0)
end

The file is a simple DIV written file containing the integer value 273. When I run this program from DIV3, result1 is always 0.

I believe this is indeed a bug since the windows version doesn't read the filesystem correctly. I will raise an issue on github and see if i can address it this week

Thanks Mike!

I am actually struggling with a different related problem: I want to use get_dirinfo (which does work on windows) to retrieve a directory listing of one of my asset data folders. However, it appears that get_dirinfo is always executed from the DIV executables path, not the path of the program. This means I can't dynamically load data files from my game folder unless I predetermine the path in code (which won't be the same for users on another machine).

Any tips? Is it possible in a DIV program to retrieve the value of what's in exec.path?

Hi Casper,

GET_DIRINFO is one of the functions I have in the list to be implemented.

It simply does not work for windows because it uses search functions for UNIX and DOS, it is necessary to implement the version with the appropriate WINDOWS functions to work well.

At the moment it will not work any way you try.

Hey CicTec,

That's interesting... because I do manage to get some information about the files in a directory using get_dirinfo()... perhaps Windows has a fallback for old DOS commands?

has some fallbacks probably, but to properly list the files and their names you need the native functions of the Windows API, especially to work properly in the latest versions like Windows 8 and 10.
