The same way that you implement different traps for different portions of a shell script that does not use functions. You can use 'trap -p' to save off the previous trap definition, install your new trap, then when done with your code, call trap to set things back to the value you saved off earlier.

Or, by creating a subshell within the body of your function, and changing the traps local to that subshell.
