Im having an issue
I can link to the C header file pty.h
(http://man7.org/linux/man-pages/man3/openpty.3.html) and call
forkpty like here:
http://dpaste.dzfl.pl/c3b07855
You have to compile that by linking with the util library
( add "libs-posix": ["util"] to dubs package.json )
For ease of reference, the main function is:
import std.stdio;
import pty;
void main(){
int master, slave;
char[16] name;
int pid = forkpty(&master, &name[0], null, null);
writefln("PID: %s", pid);
writefln("Master : %s", master);
writefln("Filename: %s", name);
}
If I run that I get:
~/Projects/D/dexpect$ ./dexpect
PID: 2224
Master : 3
Filename: /dev/pts/6�����
(As you can see, I'm attempting to create a D version of the
expect library, good way to learn some of the intricacies of D
and will be useful I suspect)
What I get back is a file name and a File Descriptor to the
master side of the pty.
How do I then open this file and perform IO on it, preferably in
a D way (std.stdio.File hopefully) rather than through C's mess
of function calls?
If I open /dev/pts/6 with File("/dev/pts/6", "rw") and attempt to
write to it, I get a "Bad file descriptor" error.
Reading from that file blocks (which I think is correct...)
Anyone have any experience with this?
As an aside, I'd prefer to do this in a pure D way, and not have
to compile against any external C libraries, does anyone know if
it is possible to spawn a pty in D without resorting to calling
external C libs?
Sorry for the long post!
Thanks
