NAME

IO::Pty::HalfDuplex::Shell - Internal module used by IO::Pty::HalfDuplex

SYNOPSIS

IO::Pty::HalfDuplex::Shell->new(ctl_pipe => $r1, info_pipe => $r2,
    command => [@_]);

DESCRIPTION

This module implements the fake shell used by IO::Pty::HalfDuplex, and is not intended to be used directly. The new function runs the shell with command as its only child, and sends its pid in 4 bytes on info_pipe.

Each time an 's' is received on ctl_pipe, the child process is allowed to continue; a 'r' will be transmitted on info_pipe if the process blocks on input, or a 'd' followed by signal and exit status (as bytes) if the process dies.

See IO::Pty::HalfDuplex.
