-.SH NAME
-gets \- get a string from standard input (DEPRECATED)
-.SH LIBRARY
-Standard C library
-.RI ( libc ", " \-lc )
-.SH SYNOPSIS
-.nf
-.B #include <stdio.h>
-.P
-.BI "[[deprecated]] char *gets(char *" "s" );
-.fi
-.SH DESCRIPTION
-.IR "Never use this function" .
-.P
-.BR gets ()
-reads a line from
-.I stdin
-into the buffer pointed to by
-.I s
-until either a terminating newline or
-.BR EOF ,
-which it replaces with a null byte (\[aq]\e0\[aq]).
-No check for buffer overrun is performed (see BUGS below).
-.SH RETURN VALUE
-.BR gets ()
-returns
-.I 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.
-.SH ATTRIBUTES
-For an explanation of the terms used in this section, see
-.BR attributes (7).

-.SH STANDARDS
-POSIX.1-2008.
-.SH HISTORY
-C89, POSIX.1-2001.
-.P
-LSB deprecates
-.BR gets ().
-POSIX.1-2008 marks
-.BR gets ()
-obsolescent.
-ISO C11 removes the specification of
-.BR gets ()
-from the C language, and since glibc 2.16,
-glibc header files don't expose the function declaration if the
-.B _ISOC11_SOURCE
-feature test macro is defined.
-.SH BUGS
-Never use
-.BR gets ().
-Because it is impossible to tell without knowing the data in advance how many
-characters
-.BR gets ()
-will read, and because
-.BR 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
-.BR fgets ()
-instead.
-.P
-For more information, see CWE-242 (aka "Use of Inherently Dangerous
-Function") at
