How to access a struct within a struct?

Can someone tell me how to do this? Just a thought that entered my mind when learning about structs. First thought was: struct one { struct two; } struct two { three; } one->two->three would this be how you would access "three"?

Struct Initialization

Hi We are using a code generator for initializing structures with the #define macro. Compiling it with the GCC 2.8.1 (with -ansi) it OK. But when we are using the SUN C 5.0 compiler it screams. Following is a code sample: #include <stdlib.h> #include <stdio.h> typedef struct TEST3 {...

openpty

OPENPTY(3)						   BSD Library Functions Manual 						OPENPTY(3)

NAME

     openpty, login_tty, forkpty -- tty utility functions

SYNOPSIS

     #include <util.h>

     int
     openpty(int *amaster, int *aslave, char *name, struct termios *termp, struct winsize *winp);

     int
     login_tty(int fd);

     pid_t
     forkpty(int *amaster, char *name, struct termios *termp, struct winsize *winp);

DESCRIPTION

     The openpty(), login_tty(), and forkpty() functions perform manipulations on ttys and pseudo-ttys.

     The openpty() function allocates a pseudo-tty and returns file descriptors for the master and slave in amaster and aslave.  If name is non-
     null, the filename of the slave is returned in name.  If termp is non-null, the terminal parameters of the slave will be set to the values in
     termp.  If winp is non-null, the window size of the slave will be set to the values in winp.

     The login_tty() function prepares for a login on the tty fd (which may be a real tty device, or the slave of a pseudo-tty as returned by
     openpty()) by creating a new session, making fd the controlling terminal for the current process, setting fd to be the standard input, out-
     put, and error streams of the current process, and closing fd.

     The forkpty() function combines openpty(), fork(), and login_tty() to creates a new process operating in a pseudo-tty.  The file descriptor
     of the master side of the pseudo-tty is returned in amaster, and the filename of the slave in name if it is non-null.  The termp and winp
     parameters, if non-null, will determine the terminal attributes and window size of the slave side of the pseudo-tty.

RETURN VALUES

     If a call to openpty(), login_tty(), or forkpty() is not successful, -1 is returned and errno is set to indicate the error.  Otherwise,
     openpty(), login_tty(), and the child process of forkpty() return 0, and the parent process of forkpty() returns the process ID of the child
     process.

ERRORS

     openpty() will fail if:

     [EAGAIN]		There are no available pseudo-ttys.

     login_tty() will fail if ioctl() fails to set fd to the controlling terminal of the current process.  forkpty() will fail if either openpty()
     or fork() fails.

FILES

     /dev/ptmx		       cloning pseudo-tty device
     /dev/ttys[0-9][0-9][0-9]  slave pseudo-tty devices
