aa_init
=======

     #include <aalib.h>


     aa_context *aa_init
     (
         const struct aa_driver *driver,
         const struct aa_hardware_params *defparams,
         const void *driverdata
     );

Parameters
==========

    `const struct aa_driver *driver'
          Driver you want to use.  Available drivers are listed in the
          NULL terminated aa_drivers array.

    `const struct aa_hardware_params *defparams'
          Hardware parameters you want.  Use aa_defparams for default
          values.

    `const void *driverdata'
          This pointer is passed dirrectly to driver used to specify
          additional driver dependent parameters.

Description
===========

This is the most primitive AA-lib initialization function.  Allows
better control over the process than the easier to use aa_autoinit
function.

   Every AA-lib program ought to have call to aa_parseoptions before
first call to aa_init.

Return value
============

Pointer to new AA-lib context or NULL if failed.
