One note, although the errNo procedure allows you to assign a value
to the errNo memory, but it is not recommended to do so, generally.


The C documentation for errno says this:

"Your program should always initialize errno to 0 (zero) before calling a function because errno is not reset by any library functions. Check for the value of errno immediately after calling the function that you want to check. You should also initialize errno to zero after an error has occurred."
