ftell error after the first call to fread

Question

So I have a very simple program that reads the 3 first bytes of a file:

int main(void)

{

    FILE *fd = NULL;
    int i;
    unsigned char test = 0;
    fd = fopen(         


        

Answer 1

You need to open the file in binary mode:

fd = fopen("test.bmp", "rb");

If you try to read a binary file like a bitmap in text mode, the bytes corresponding to carriage returns and linefeeds confuse things.
