first ,I'am chinese . my english is poor. But I am in the linux .
the marco use to list :
1. replace the const number called magic number
2. like C++ inline funciton,for example:
#define IS_LEAR_YEAR(y) y % 4 == 0 && y % 100 != 0 || y % 400 == 0
3.uses to debug
#define DBGprint(...) printf("DEBUG:%s", __VA_ARGS__)
4. uses the # and ##
the # uses like add "
## example:
#define Command##x the result is Command_x
