The following form allows you to view linux man pages.
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 ver-
sion 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.
