NAME

       rtapi_init - Sets up RTAPI

SYNTAX

               int rtapi_init(const char *modname)

ARGUMENTS

       modname
              The name of this rtapi module

DESCRIPTION

       rtapi_init  sets  up  the  RTAPI.  It must be called by any module that intends to use the
       API, before any other RTAPI calls.

       modname can optionally point to a string that identifies the module.  The string  will  be
       truncated  at  RTAPI_NAME_LEN  characters.   If  modname is NULL, the system will assign a
       name.

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
       rtapi_xxx_new, rtapi_xxx_delete, and rtapi_exit.  On failure, returns an RTAPI error code.
