MoarVM’s IO has an issue.

https://github.com/MoarVM/MoarVM/issues/165

Can’t pass fd between threads

orz

But we can call libc methods via NativeCall

First, call fork(2) via NativeCall

sub fork() returns Int is native { ... }

Easy.

2nd, call waitpid(2) via NativeCall

module private { our sub waitpid(Int $pid, CArray[int] $status, Int $options) returns Int is native { ... } }

sub waitpid(Int $pid, Int $options) is export { my $status = CArray[int].new; $status[0] = 0; my $ret_pid = private::waitpid($pid, $status, $options); return ($ret_pid, $status[0]); }

Easy! (Patches welcome…)

Then,

Let’s implement BSD sockets wrapper.

I don’t recommend to use NativeCall directly.

There’s too many C types/structs.

Too many wrapper types…

Write dll in C. And call it via NativeCall.

Raw::Socket

BSD socket wrapper for Perl6

Then, write httpd.
