Not at run time.  You need to assemble the code separately, and put into 
your program an array of bytes that are the opcodes of the handler.  Then 
use memcpy or whatever to copy them.

But I really don't understand why do you need to go to such lengths?  
Can't you simply install your function, however it is written, as an 
interrupt handler?  (Section 18.9 of the DJGPP FAQ tells you how.)  Why 
do you need to copy it somewhere?
