Have a look at the BLINKEYIRQ.ZIP example in the download area of the Keil 
website.  THis shows how you can write a C function with an interrupt 
attribute. This will apply the appropriate interrupt wrappers.

I personally prefer to do my own interrupt wrappers in assembler, which might 
themselves call C functions. THis allows more flexibility and control.
