help with load function

Question

My load function loads everything except for cat.jpg and favicon.ico, cat.html will display cat.jpg though. I am unsure how to test or even begin fixing this. If anyone has any tips on how to debug or sees a problem with my code. Any help would be much appreciated thanks.

bool load(FILE* file, BYTE** content, size_t* length)
{

*content = NULL;
*length = 0;

if(file == NULL)
{
    perror("SOME ERROR");
}
char* buffer = NULL;

    int i = 0;

    for (int c = fgetc(file);c != EOF;c = fgetc(file))
    { 
        //continually allocate memory until end of file
        buffer = (char *) realloc(buffer,sizeof(char)*(i + 1));
        if(buffer == NULL)
        {
            return false;    
        }
        buffer[i] = (char) c;
        i++;
    }
    *content = &buffer[0];
    *length = i; 

return true;
}

Answer 1

Right. I won't analyze the other functions because I've found problems with lookup():

Read carefully what you're returning here:

return "text/jpeg";
return "text/gif";
return "text/x-icon";

Now read VERY CAREFULLY what the sandbox link is saying you should return.
