just select an exploit.
This is my code:

I'm having difficulty understanding the purposes of using dup/dup2 when involving forks.
for example, if we call fork() once, that is, we are creating a child process. In what cases would we need to use dup or dup2 to duplicate the file descriptors for standard output and standard error? What... (1 Reply)
Hi,

Hi, I will try to keep my post as compressed as my title was.

is it possible to duplicate file descriptors(opened by a different process) with the help of dup or dup2. the two process do not share parent child relationship as well. (2 Replies)
What this code should do is: there are parent.cpp and child.cpp. Parent will send whatever is in the buffer to child and child will send back whatever received to parent. I do not know what I am doing wrong. I am confused what is missing in the parent and what else I should include into the child.... (1 Reply)

stty
STTY(3) BSD Library Functions Manual STTY(3)NAME
stty, gtty -- set and get terminal state (defunct)
LIBRARY
Compatibility Library (libcompat, -lcompat)
SYNOPSIS
#include <sgtty.h>
stty(int fd, struct sgttyb *buf);
gtty(int fd, struct sgttyb *buf);
DESCRIPTION
These interfaces are obsoleted by ioctl(2). They are available from the compatibility library, libcompat.
The stty() function sets the state of the terminal associated with fd. The gtty() function retrieves the state of the terminal associated
with fd. To set the state of a terminal the call must have write permission.
The stty() call is actually 'ioctl(fd, TIOCSETP, buf)', while the gtty() call is 'ioctl(fd, TIOCGETP, buf)'. See ioctl(2) and tty(4) for an
explanation.
DIAGNOSTICS
If the call is successful 0 is returned, otherwise -1 is returned and the global variable errno contains the reason for the failure.
SEE ALSO ioctl(2), tty(4)HISTORY
The stty() and gtty() functions appeared in 4.2BSD.
