pack_fread − Reads n bytes from the stream. Allegro game programming library.
long pack_fread(void *p, long n, PACKFILE *f);
Reads ‘n’ bytes from the stream ‘f’, storing them at the memory location pointed to by ‘p’. Example:
unsigned char buf;
if (pack_fread(buf, 256, input_file) != 256)
abort_on_error("Truncated input file!");
Returns the number of bytes read, which will be less than ‘n’ if EOF is reached or an error occurs. Error codes are stored in errno.
