50 in the parameter slot so it can be overwritten in the caller, or
54 failure: it just raises an exception matching C</^open2:/>. However,
58 open2() does not wait for and reap the child process after it exits.
59 Except for short programs where it's acceptable to let the operating system
66 assumes it's going to talk to something like B<bc>, both writing
67 to it and reading from it. This is presumably safe because you

75 C<cat -v> and continually read and write a line from it.
