Sticker is a system call spy API which runs in
user mode. It is a user-friendly, object-oriented
wrapper around the ptrace API. Using Sticker, an
end user can utilize the benefits of ptrace
without knowing the details of the ptrace API. The
objective is to produce an API (libSticker) that
can help in speedy development of applications
that work like debuggers, code injectors, and
system call spies.
