openpty forkpty - auxiliary functions to obtain a pseudo-terminal
If the argument
copies the pathname of the slave pty to this area. The caller is responsible for allocating the required space in this array.
If the arguments
initializes the termios and window size settings from the structures these arguments point to, respectively.
Upon return, the open file descriptors for the master and slave side of the pty are returned in the locations pointed to by Fa amaster and Fa aslave , respectively.
function first calls openpty ();
to obtain the next available pseudo-terminal from the system. Upon success, it forks off a new process. In the child process, it closes the descriptor for the master side of the pty, and calls login_tty3 for the slave pty. In the parent process, it closes the descriptor for the slave side of the pty. The arguments Fa amaster , Fa name , Fa termp , and Fa winp have the same meaning as described for openpty (.);
function returns -1 on failure, 0 in the slave process, and the process ID of the slave process in the parent process.
In addition to this,
may set it to any value as described for fork(2).
