Including Autoconfiguration Header Files

All of the autoconfiguration entry point routines and all of the user context entry point routines require that you include the ddi.h and sunddi.h header files. You already included these two header files for the cmn_err(9F) function.

The ddi_create_minor_node(9F) function requires the stat.h header file. The dummy_attach() routine calls the ddi_create_minor_node(9F) function. The prop_op(9E) and the ddi_prop_op(9F) functions require the types.h header file.

The following code is the list of header files that you now should have included in your dummy.c file for the four autoconfiguration routines you have written in this section and the three loadable module configuration routines you wrote in the previous section.

#include <sys/modctl.h>  /* used by _init, _info, _fini */
#include <sys/types.h>   /* used by prop_op, ddi_prop_op */
#include <sys/stat.h>    /* defines S_IFCHR used by ddi_create_minor_node */
#include <sys/cmn_err.h> /* used by all entry points for this driver */
#include <sys/ddi.h>     /* used by all entry points for this driver */
                         /* also used by ddi_get_instance, ddi_prop_op */
#include <sys/sunddi.h>  /* used by all entry points for this driver */
                         /* also used by ddi_create_minor_node, */
                         /* ddi_get_instance, and ddi_prop_op */
