// call to "_dup2" fails, as it specifically tests to ensure that the target file number isn't equal to this value
// before allowing the operation to continue. We can resolve this issue by first "re-opening" the target files to
// use the "nul" device, which will place them into a valid state, after which we can redirect them to our target
// using the "_dup2" function.
