• Creating a directory in a Win10 console application.

    From Peter Percival@21:1/5 to All on Sat Jan 27 14:22:13 2018
    Is there a library function that will create a directory in a Win10
    console application? I can call system("mkdir") but am looking for
    something like fopen(dirname, "w").

    f = fopen(".\\dir\\", "w"); /* With .\\dir\\ not existing */
    i = ferror(f);

    crashes because (it seems) ferror doesn't like a NULL argument. (Nor
    does it create .\\dir\\ before crashing!)

    Trying to use creat produces error message "undefined reference to
    creat". Presumably that's the linker.

    Is that callable in console applications?

    Yes, this code will create a directory named 'mymkdir' (under the
    current directory:

    #include <stdio.h>
    #include <windows.h>

    int main()
    {
    CreateDirectory("mymkdir", NULL);
    return 0;
    }

    There is also mkdir in direct.h

    Had you not drawn that to my attention it would not have occurred to me
    to wonder about the difference! Thanks.
