I am porting my C++ OpenGL application to iOS, it uses getcwd function to load shaders. In iOS 'getcwd' returns just a slash and I can't do something. Or is there any good method to load files on iOS?

Edit: found a solution! POSIX-based code.

static char homePath[256];
char *DocumentsFolder(void)
{

char *p;

if (*homePath)
    return homePath;

if ((p = getenv("HOME")) != NULL) {
    strncpy(homePath, p, sizeof(homePath));

    strcat(homePath, "/Documents" );
    if (mkdir(homePath, 0777)) {
        if (errno != EEXIST)
            printf( "CAN NOT CREATE DIRECTORY\n" );
    }
    return homePath;
}
return ""; 
}

If you can use Objective-C, see `NSFileManager`. It has a method to get the current working directory. – rmaddy Oct 07 '14 at 21:21
where are the shader files? – Sam Miller Oct 07 '14 at 21:32
I've placed them in xcode project/Data/shaders/shaderfile. – neko_code Oct 07 '14 at 21:38
@MarcB You are kidding? Honestly, you need to understand sandboxing, bundles and "well known" folders. Actually, there are files and there's a filesystem, too of course. – CouchDeveloper Oct 08 '14 at 06:16
Well, I managed this out by dropping files to /Documents/ and using code at top. – neko_code Oct 08 '14 at 08:51
