From 4e3973b457d42172711e2c556362826b02c44169 Mon Sep 17 00:00:00 2001 From: Benjamin Kaduk Date: Fri, 28 Oct 2016 11:53:00 -0500 Subject: [PATCH] Try to unify BIO read/write parameter names After the recent reworking, not everything matched up, and some comments didn't catch up to the outl-->dlen and inl-->dlen renames that happened during the development of the recent patches. Try to make parameter names consistent across header, implementation, and manual pages. Also remove some trailing whitespace that was inadvertently introduced.
