# Pete
A friendly wrapper around the Linux `ptrace(2)` syscall.
## Summary
The `ptrace(2)` interface entails interpreting a series of `wait(2)` statuses. The context used to
interpret a status includes the attach options set on each tracee, previously-seen stops, recent
ptrace requests, and in some cases, extra event data that must be queried using additional ptrace
calls.
Pete is meant to instead permit reasoning directly about ptrace-stops, as described in the manual.
We hide the lowest-level contextual bookkeeping required to disambiguate ptrace-stops. Whenever we
can, we avoid extraneous ptrace calls, deferring to downstream tracers implemented on top of the
library. For example, Pete can distinguish a syscall-enter-stop and syscall-exit-stop, but does not
_automatically_ query register state to identify the specific syscall.
