Opening /dev/ent0

[P. D. Feighery]

Greetings:

On our RS/6000 I`ve been trying to create my own system calls via kernel
externsions.  Sofar so good.  In one of my new system calls I am trying to
open the device /dev/ent0 via fp_open.  Unfortunately fp_open returns error
code 22 (Invalid argument).  Does anyone know the proper way to open a device
(/dev/ent0 in particular).

Is fp_open the correct method, is there some way to use entopen directly,
or is their a better approach?  Any suggestions would be greatly appreciated.
