Well to me it would seem pretty obvious from the link I sent !
In Ronald's example he writes to a bit using GIE = 1 so to read you can do if ( GIE == 1 ). You need to set up a #byte for ADCON0 and a #bit for the bit you want to read.

Expanding on what andyfraser said, you really should take time to read the manual. See #bit in the pre-processor section of the manual. It shows how to define a register bit reference.

In the link he cited, rnielsen (Ron) provides a great example that would answer your question if you would just take a look.
