Name            gets - gets a string from a stream

Usage           char *gets(char *string);

Prototype in    stdio.h

Description     gets reads a string into string from the
                standard input stream stdin. The string is terminated by a
                newline character, which is replaced in @i{string} by a null
                character (\0).

Return value    on success, returns the string argument string;
                else returns NULL on end-of-file or error.
