hi im working on a little app for DS & im kinda stuck.
i have the file directories showing. but i kinda need some help scanning trough them like selecting folders & opening/closing them.
sorta like how that one example called all in one where it has a simple menu.
i cant seem to figure it out
my code is similar to the libfat code.
but how to surch trugh directories it shows?

can you be a little more specific - I am not sure what you are asking. can you show what you are trying to do, how you are trying to do it, and why you think it is not working?

I think he meant he wants the source code for open a directory (folder) and to show the filenames in this directory (folder).

yes exactly that, sorry wasnt so spacific,
like i have the code where the folder directories are showing. but im having problems comming up with something to look trugh the folders.
heres the code
Code: Select all
//---------------------------------------------------------------------------------
int main(int argc, char **argv) {
//---------------------------------------------------------------------------------
videoSetMode(MODE_0_2D);
videoSetModeSub(MODE_0_2D);
PrintConsole topScreen;
vramSetBankA(VRAM_A_MAIN_BG);
consoleInit(&topScreen, 0,BgType_Text4bpp, BgSize_T_256x256, 31, 0, true, true);
PrintConsole bottomScreen;
consoleSelect(&topScreen);
//1-7 after 3 for color
iprintf("\x1b[34;1miLauncher 000\n");
vramSetBankC(VRAM_C_SUB_BG);
consoleInit(&bottomScreen, 0,BgType_Text4bpp, BgSize_T_256x256, 31, 0, false, true);
BG_PALETTE_SUB[0] = RGB15( 0, 0, 20 );
consoleSelect(&bottomScreen);
if (fatInitDefault())
{
DIR *pdir;
struct dirent *pent;
struct stat statbuf;
pdir=opendir("/");
if (pdir)
{
while ((pent=readdir(pdir))!=NULL)
{
stat(pent->d_name,&statbuf);
if(strcmp(".", pent->d_name) == 0 || strcmp("..", pent->d_name) == 0)continue;
if(S_ISDIR(statbuf.st_mode))
iprintf("%s <dir>\n", pent->d_name);
if(!(S_ISDIR(statbuf.st_mode)))
iprintf("%s %ld\n", pent->d_name, statbuf.st_size);
}
closedir(pdir);
}
else
{
iprintf("opendir() failure; terminating\n");
}
}
//if fails
else
{
iprintf("fatInitDefault failure: terminating\n");
}
while(1) {
//swiWaitForVBlank();
}
return 0;
}

Sorry can you please post your hole source and maybe your Makefile, because compiling this short piece of code isn't possible!

Hi. It might be worth your while looking at devkitpro/examples/nds/filesystem/nitrofs and libfat.
The nitrofs example seems to fill your requirement.

Well, it seems that you changed the Makefile a bit:
You have to add the libfat in your makefile right?
I will test your app now...
