gets - get a string from standard input (DEPRECATED)


   #include <stdio.h>

   char *gets(char *s);


   Never use this function.

   gets()  reads  a  line from stdin into the buffer pointed to by s until
   either a terminating newline or EOF, which it replaces with a null byte
   ('\0').  No check for buffer overrun is performed (see BUGS below).


   gets()  returns  s  on  success,  and NULL on error or when end of file
   occurs while no characters have been read.  However, given the lack  of
   buffer  overrun  checking, there can be no guarantees that the function
   will even return.

   C89, C99, POSIX.1-2001.

   LSB deprecates gets().  POSIX.1-2008 marks gets() obsolescent.  ISO C11
   removes the specification of gets() from  the  C  language,  and  since
   version  2.16, glibc header files don't expose the function declaration
   if the _ISOC11_SOURCE feature test macro is defined.


   Never use gets().  Because it is impossible to tell without knowing the
   data  in  advance  how  many  characters  gets() will read, and because
   gets() will continue to store characters past the end of the buffer, it
   is  extremely  dangerous  to  use.   It has been used to break computer
   security.  Use fgets() instead.
