Well, it's not conmpletely obvious, but the other routine mentioned in
the same man-page is the better solution.

Instead of:

{
   char foo[255];
   char *ptr;

#if defined(BAD_CODE)
   gets(foo);
#else
   fgets(foo, 255, stdin);
   c = index(foo, '\n');
   if ( c != NULL )
      *c = '\0';
#endif

}
   
The use of the index call is necessary to strip off the trailing '\n'.
