Hi,
I wrote an fdisk program which uses several read(2) and write(2).
My program should compile on any unix that uses sane libc.
If compile it will work, except on systems that use geom methods.
I read that geom is accessed via struct BIO.
I can write a version of my program using struct BIO.
I'm sure it will compile and work.
Now should I maintain different version my program?
Or should I write a set of function for each method, then some code to
detect whatever method the kernel is using and use the appropriate set of
functions.
Also, I'm thinking, would it be a good idea to have another API to
interface every other devices API. Like:
Parent /dev using Master Device API
Child /dev/disk using GEOM API
Child /dev/net using NET API
. . .
. . .
. . .
I'm a bit confussed...

thanks for reading
