You need to use virtual mode. I don't know how straightforward it is
to do this from C. You could look at the DOSemu code; that uses
virtual mode.
I suspect that you will need a book on the 386 family. The yellow one
from Microsoft Press is actually quite good.
Also, you will need to ensure that calling the BIOS functions doesn't
do anything which will confuse the kernel (e.g. changing the state of
any hardware).
