    Command:

    gets

    
    
    

    SYNOPSIS

           #include <stdio.h>
    
           char *gets(char *s);
    
    
    

    DESCRIPTION

           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).
    
    
    

    RETURN VALUE

           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.
    
    
    

    CONFORMING TO

           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 ver-
           sion 2.16, glibc header files don't expose the function declaration  if
           the _ISOC11_SOURCE feature test macro is defined.
    
    
    

    BUGS

           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.

           Function") at http://cwe.mitre.org/data/definitions/242.html
