Homebrew FSUSER_OpenFileDirectly compile error

[tibinago]

Hi again,

I am very new to coding hence why I asked a simiular question yesterday. To start learning to code I thought I'd take a source code and try to add some simple stuff to that.
I used 3DSController 0.6 for that because I thought some simple changes would make it better for me.

It turned out that the code is outdated especially functions that used ctrtulib. With some fiddling around I managed to update the code and reduce the errors to just one but this one gave me headaches.

I have trouble getting FSUSER_OpenFileDirectly to work.
Attached you can find the error messages.

By removing the '&' in front of &fileHandle the first error gets fixed, but is that the right way?
Secondly smdcArchive gets an error aswell but I cant figure out how to fix it. Examples I found on the internet unfortunately didn't help me. Any ideas?


Btw does anybody know a good way to learn to code? I have some very basic (pun intended) java experience from highschool but that's about it.


Thank you in advance!


This is settings.c

#include <3ds.h>

#include "wireless.h"

#include "settings.h"

static bool getSetting(char *name, char *src, char *dest) {

        strncpy(dest, start, size);
        dest[size] = '\0';
        
        return true;
    }

    if(ret) return false;
    
    memcpy(&settings, &defaultSettings, sizeof(struct settings));

    }
    
    free(buffer);
    
    return true;
}

There is a sticky development thread where you can ask question, you don't need to create a new post every time.

Basically you're going to have to find some c lessons on the internet. The compiler is literally highlighting the problems for you.
