DLKM WSIO Interface Drivers

[Hervé Barale]

I am porting Statically linked WSIO Interface Driver
from HP-UX 10.20 to HP-UX 11.0, for that i have
decided to use the DLKM mechanism, and to set
dynamically loadable my driver.
But When I try to use the example given for
the initialization, the compilation failed with the
following error :
error 1588 "MOD_WSIO_CORE" undefined
at the 'C' line:
mod_wsio_attach_list_add(MOD_WSIO_CORE, ...);

I have not found this type by greping in include files.
I have followed the HP document :
"Developing Dynamically Loadable Kernel Modules"
- Is this part wrong or not fully detailed ?
- Do you have any Idea about this part ?

There was a problem where the HPUX-11 headers had not defined the MOD_WSIO_xxx this was meant to be fixed but you might have to apply a patch. The best bet is to log a call with HP and see if the SR is still open.
