Why my gets function is not working in C?

How do I stop getting warnings?

1. If you _really_ want to suppress the compile and linker warnings, you can do something like.
2. (in some top-level include file):
3. extern char *my_gets(char *);
4. #define gets(str) my_gets(str)
5. (in some app utility file)
6. char * my_gets(char *str)
7. {
8. This will defeat the compiler and linker warnings.

Why do we use gets in C?
