Pointers pointers pointers...
This should be an easy one, needless to say I don't know it :)
I've made a small program that allocates a 64,000 byte buffer, reads data from a file into it and then opens another file and writes it. However, after compiling it in Turbo C++ 3.0 and then running it, Windows catches a general protection fault (a crash in real DOS). The problem is, I'm not sure why...
Here's the code:-
The actual program won't always allocate 64,000 bytes each time, so a static buffer isn't the answer. I have a feeling I'm misusing pointers here. Any ideas?
unsigned char *screen;
fp = fopen("image", "rb");
screen = (unsigned char *)malloc(64000);
fread(screen, 64000, 1, fp);
fp = fopen("data.raw", "wb");
fwrite(screen, 64000, 1, fp);
