char *<[buf]>;

DESCRIPTION
|
|
|
|
Reads characters from standard input until a newline is found.
|
|
|
|
The characters up to the newline are stored in <[buf]>. The
|
|
|
|
newline is discarded, and the buffer is terminated with a 0.
|
|
|
|
|
|
|
|
This is a @emph{dangerous} function, as it has no way of checking
|
|
|
|
the amount of space available in <[buf]>. One of the attacks
|
|
|
|
used by the Internet Worm of 1988 used this to overrun a
|
|
|
|
buffer allocated on the stack of the finger daemon and
|
|
|
|
overwrite the return address, causing the daemon to execute
|
|
|
|
code downloaded into it over the connection.
|
|
|
|
|
|
|
|
The alternate function <<_gets_r>> is a reentrant version. The extra
|
|
|
|
argument <[reent]> is a pointer to a reentrancy structure.
|
|
|
|
|
|
|
|
|
|
|
|
RETURNS
|
|
|
|
<<gets>> returns the buffer passed to it, with the data filled
|
|
|
|
in. If end of file occurs with some data already accumulated,
|
|
|
|
the data is returned with no other indication. If end of file
|
|
|
|
occurs with no data in the buffer, NULL is returned.
|
|
|
|
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
