Full Name:
  The libunwind project

System Group Name:

  non-GNU software & documentation

  X11 license

  The libunwind project defines a portable and efficient C programming
interface (API) to determine the call-chain of a program. The API
additionally provides the means to manipulate the preserved (callee-saved)
state of each call-frame and to resume execution at any point in the
call-chain (non-local goto). The API supports both local (same-process) and
remote (across-process) operation. As such, the API is useful in a number of
applications. Some examples include:

o exception handling
    The libunwind API makes it trivial to implement the
    stack-manipulation aspects of exception handling. 
o debuggers
    The libunwind API makes it trivial for debuggers to generate
    the call-chain (backtrace) of the threads in a running program. 
o introspection
    It is often useful for a running thread to determine its
    call-chain. For example, this is useful to display error
    messages (to show how the error came about) and for performance
o efficient setjmp()
    With libunwind, it is possible to implement an extremely
    efficient version of setjmp(). Effectively, the only context
    that needs to be saved consists of the stack-pointer(s). 

The current libunwind code is hosted at:

The libunwind API and its implementation are licensed under an X11-style
license.  The libunwind code currently works best on GNU/Linux for Itanium,
but improved support for DWARF-based platforms, such as GNU/Linux for x86 and
x86-64 is under active development.  Libunwind can run on non-free OSes (e.g.,
there is rudimentary support for HP-UX), but that's not a priority.

Other Software Required:
  None (other than minimal dependencies on the system's C runtime library).
