DESCRIPTION

       hal_init  sets  up HAL and RTAPI.  It must be called by any module that intends to use the

       modname must point to a string that identifies the module.  The string may  be  no  longer
       than HAL_NAME_LEN characters.

REALTIME CONSIDERATIONS

       Call only from within user or init/cleanup code, not from relatime tasks.

RETURN VALUE

       On  success,  returns  a positive integer module ID, which is used for subsequent calls to
       hal and rtapi APIs.  On failure, returns a HAL error code.
