ptr_inspect.c
Demonstration code; shows how to trace the system calls in a child
process with ptrace. Only works on 64-bit x86 Linux for now, I'm
afraid. (Even worse, it's only tested on Linux 2.6....)
The callname() function looks clunky and machine-generated because it

Continuous build on the cheap, using inotify, cmake and a terminal
#!/bin/bash
# Watch paths (given as arguments), automatically build when something changes.
# The script does a couple opinionated things to make my life easier:
#
# * Terminal scrollbuffer is reset before each iteration, simplifying scrolling.
# * I use a filter script to colorize gcc output (clang errors would be nicer).
# * Output is copied to a log file (/tmp/build.log).
# - I open this file in Sublime or vim, which reloads the file on change (each build).

// bit_cast<Dest,Source> is a template function that implements the
