Problems with NitroFS

[thiagoauler]

Hi, everyone,

This is my question:
Does someone know why fopen call is not working??

Here is my code:

Code: Select all

#include <nds.h>
#incluide <filesystem.h>
#include <stdio.h>

int main(void)
{
consoleDemoInit();
nitroFSInit();
FILE *f = fopen("nitro:/hello_world.txt", "rb");
if (f != NULL)
{
	fscanf(f, "%s", str);
	printf("%s", str);
}
else
	printf("error!");

return 0;
}

I'm using the nitrofs example as basis...

TIA

need the context that it's not working in - emulator, hardware etc...

Basically put down everything that you've done to get to that point, where's the files stored in your nitro folder, how your testing etc...

Hi...

The example I'm using as basis can be found here:
<devkitPro>\examples\nds\filesystem\nitrofs\nitrodir

This example worked fine, I tested using no$gba.
But the "problem" is when I did some modifications to use "FILE *fopen(...)" instead of "DIR *diropen(...)"

The filesystem files are inside a folder called nitrofiles... and I just added mine for testing...
Ahh, very important... no error on compiling and executing...
The actual problems happens in fopen command... it returns an NULL handle

Man... i just can't believe...

I put hello_world.txt.txt in my folder...


what a mistake.... lol
now it's working like a charm!

thanks

you didn't declare str btw...
well, when it tried to declare
char* str;
the result is (null).. but when i convert it as integer
int str
it works... (as long as the text only consist number , like 1, 2 etc)
