  OSSP ex - Exception Handling
  Version 1.0.2 (30-Jan-2003)

  ABSTRACT

  OSSP ex is a small ISO-C++ style exception handling library for use in
  the ISO-C language. It allows you to use the paradigm of throwing and
  catching exceptions in order to reduce the amount of error handling
  code without making your program less robust.

  This is achieved by directly transferring exceptional return codes
  (and the program control flow) from the location where the exception
  is raised (throw point) to the location where it is handled (catch
  point) -- usually from a deeply nested sub-routine to a parent
  routine. All intermediate routines no longer have to make sure that
  the exceptional return codes from sub-routines are correctly passed
  back to the parent.

  The OSSP ex facility also provides advanced exception handling
  features like shielded and deferred exceptions. Additionally, OSSP ex
  allows you to choose the used underlying machine context switching
  facility and optionally support multi-threading environments by
  allowing you to store the exception catching stack in a thread-safe
  way.
