perl-IPC-Open3 - open a process for reading, writing, and error handling using open3()
- Description:
Extremely similar to open2(), open3() spawns the given $cmd and
connects CHLD_OUT for reading from the child, CHLD_IN for writing to
the child, and CHLD_ERR for errors. If CHLD_ERR is false, or the
same file descriptor as CHLD_OUT, then STDOUT and STDERR of the child
are on the same filehandle (this means that an autovivified lexical
cannot be used for the STDERR filehandle, see SYNOPSIS). The CHLD_IN
will have autoflush turned on.
