openwrt mtr - add small function using source code -- 2

I am not sure which language the source will be in so could be something other than C. Need someone to add a small function into the mtr source code. The change would allow mtr to run continuously until sending a trigger to end the process but making sure that it outputs it's report. This would allow me to use mtr inside of a script. At this time, mtr can only be used from command line using it's report function. This must work on openwrt OS for small wireless router.
