CCoding Style - Function Macros
- There is a tendency among C-Programmers to write macros instead of functions for short computations that will be executed frequently.
- The reason is performance: a macro avoids the overhead of a function call.
- With modern machines and compilers, the drawbacks of function macros outweighs their benefits.
- Function macros cause more problems than they solve.
- If you insist on using function macros, be careful.
