This is of course a question for the list as a whole... :-)

But, you put that anywhare in your C source just as you
would do with any other C function definition.

A short cut down example from a working code
using a Timer0 interrupt:

------------------------------------------------
// CONFIG1
....
// CONFIG2
#pragma config WRT =3D OFF
....

#include <xc.h>

void interrupt myint (void) {
     if (TMR0IE && TMR0IF) {
         TMR0IF =3D 0;
....
....
         return;
     }
}

void init(void){
....
....
// Setup of ports, timers, interrupts and so on.
     return;
}

void main(void) {
     init();
     ei();
     while (1) {}
  }
------------------------------------------------
