24. Inline Functions

Question.2

A developer marks a 50-line function with loops and switch-cases as inline:

inline void process_packet(uint8_t *buf, int len) {
   // 50 lines with loops and switch
   for (int i = 0; i < len; i++) {
       switch (buf[i]) { /* ... */ }
   }
}

Will the compiler inline this?

Need Help? Refer to the Quick Guide below

Yes — the inline keyword forces inlining
Yes — but only with -O2 or higher optimization
No — inline is a request, not a command
No — inline cannot be used with functions containing loops
