(ruby) Broken pipe (Errno::EPIPE)

Question

i have a Broken pipe (Errno::EPIPE) error popping up and i don't understand what it is or how to fix it. the full error is:

example.rb:19:in `write': Broken pipe (Errno::EPIPE)
    from example.rb:19:in `print'
    from example.rb:19

line 19 of my code is:

vari.print("x=" + my_val + "&y=1&z=Add+Num\r\n")

Answer 1

It means that whatever connection print is outputting to is no longer connected. Presumably the program began as input to some other program:

 % ruby_program | another_program

What's happened is that another_program has exited sometime before the print in question.
