Example of memory addressing in C
#include <stdint.h>
#include <stddef.h>
#include <stdio.h>
struct S {
// This is complicated by padding, but:
// NB: sizeof(int32_t) = 4 bytes (32 bits)
// base_address + 0

komiga / bad-seek.cpp
Last active December 25, 2015 21:58
Bad seek behavior with libc++ (svn, rev 192988). There's a patch down there.
#include <cassert>
#include <streambuf>
#include <iostream>
// Dummy stream buffer for testing.
// basic_streambuf defines seekoff() and seekpos() (virtuals) to
// return pos_type(off_type(-1)), which indicates a seek failure, so
// we don't really have to define them, but I've done so for the sake
// of pedantry.
