Homebrew Discussion Read txt problem

[jonyluke]

I am working in a project,but i am having problems reading a txt file


dir = opendir("");
FILE *f = fopen("attach.txt", "r");
char att[30];
char natt[30];
fgets(att, sizeof(att), f);
fgets(natt, sizeof(natt), f);
fclose(f);
playMp3(att);
playMp3(natt);


It does not sound, however when i put playMp3("ting.mp3"); it sounds, so the problem is about reading the txt file

That is not how troubleshooting works. All you know is that, if you hardcode the sound file, it works. You don't know the following:

• is the textfile being read
• is it being read correctly
• What is being returned when you call fgets

To sum it up, you don't know quite a lot

man fgets

fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline. If a newline is read, it is stored into the buffer. A terminating null byte ('\0') is stored after the last character in the buffer.

I found a solution, dir = opendir("sdmc:/");
