// Function: pty_fork
//
// Purpose:
// Like fork(), but creates a PTY and returns its file descriptor/name.
//
// Arguments:
// fdm : new file descriptor
// slave_name: new pty path
//
// Programmer: Jeremy Meredith
// Creation: April 27, 2001
//
// Modifications:
// Jeremy Meredith, Tue Oct 22 15:00:37 PDT 2002
// Added an optional signal child handler. Since setting this must happen
// before fork() and after grantpt(), it must be set in this function.

* NAME
* fork_pty() -- Opens a pty, forks and redirects the std handles
*
* SYNOPSIS
* pid_t fork_pty(int *ptrfdm, int *fd_pipe_err, dstring *err_msg)
*
* FUNCTION
* Opens a pty, forks and redirects stdin, stdout and stderr of the child
* to the pty.
*
* INPUTS
* int *ptrfdm - Receives the file descriptor of the master side of
* the pty.
* int *fd_pipe_err - A int[2] array that receives the file descriptors
* of a pipe to separately redirect stderr.
* To achieve the same behaviour like rlogin/rsh, this
* is normally disabled, compile with
* -DUSE_PTY_AND_PIPE_ERR to enable this feature.
* dstring *err_msg - Receives an error string in case of error.
*
* RESULT
* pid_t - -1 in case of error,
* 0 in the child process,
* or the pid of the child process in the parent process.
*
* NOTES
* MT-NOTE: fork_pty() is not MT safe
*
* SEE ALSO
* pty/fork_no_pty
