counter. Some devices, e.g. __/dev/null__ do not cause the error [ESPIPE], but return a pointer which value is undefined.

This document's use of ''whence'' is incorrect English, but maintained for historical (hysterical?) reasons.
When converting old code, substitute values for ''whence'' with the following macros:
