/*! \file ida.hpp

  \brief Contains the ::inf structure definition and some
         functions common to the whole IDA project.

  The ::inf structure is saved in the database and contains information
  specific to the current program being disassembled.
  Initially it is filled with values from ida.cfg.

  Although it is not a good idea to change values in ::inf
  structure (because you will overwrite values taken from ida.cfg),
  you are allowed to do it if you feel it necessary.
