This is a thoughtful request. The (for dsPIC30/33 and PIC24 families) is now legacy (superseded by XC16), but many engineers still maintain projects on it. if (next_head == cb-&gt

// Example: MAC with saturation inline int mac_saturate(int acc, int a, int b) acc += a * b; if (acc > 32767) acc = 32767; if (acc < -32768) acc = -32768; return acc;
