The get_stack_trace syscall generates a stack trace using the kernel debugging facilities and copies the resulting return address array to the preallocated buffer from userland. It is only possible to get a stack trace of the current thread. The lookup_symbol syscall can be used to look up the symbol and image name corresponding to an address. It can be used to resolve symbols from a stack trace generated by the get_stack_trace syscall. Only symbols of the current team can be looked up. Note that this uses the symbol lookup of the kernel debugger which does not support lookup of all symbols (static functions are missing for example). This is meant to be used in situations where more elaborate stack trace generation, like done in the userland debugging helpers, is not possible due to constraints.
Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!

Contributing documentation
The main piece of documentation that still needs work are the API docs (found
in the tree at src/docs/user). Just find an undocumented class, write
documentation for it, and submit a patch.
