I am trying to write drivers that should be "Solaris compliant". By this I mean that the driver should be - DDI or DKI or LDI compliant. Now my doubts are:
1. There are extern decelerations in header files available in solaris. Can we use then directly while writing our kernel modules or not?
2. I assume the LDI is a subset of DDI/DKI interfaces...now my confusion is, should a driver be DDI or DKI or LDI complient or all?
3. Certain DDI interfaces, like ddi_pathname_to_dev_t, do not have man pages. Does this mean that it is not a public interface? Then why is it a DDI interface? DDI is supposed to be public and make drivers portable right?
Thanks for the help!
