pe-unwind-info

A zero-copy parser for the contents of the .pdata section and unwind info structures (typically addressed by the contents of the .pdata section).

This library provides low-level, efficient parsers for the function tables in .pdata as well as unwind info structures in other places. On top of this functionality, higher-level functionality to unwind an entire frame (given a module's contents) is provided. This only copies data as necessary. No heap allocations are needed.

This currently targets x86_64 PE modules. ARM64 support will be added soon.

This library assumes all information is little-endian: as far as I can tell, Windows always either targets little-endian-only CPUs or configures CPUs which support little- and big-endian to be little-endian.
