From ee507ce9a1e8ef58e75ca3b59bc3db44313c661c Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Tue, 11 Dec 2018 09:42:20 +0100 Subject: [PATCH] modify parse_size_and_unit() to support percentage Modify parse_size_and_unit() to support a value followed by a '%' character. In this case ps is required to be non-NULL to ensure the caller can detect that case. The returned value will be the integer value s was pointing to and *ps will point to the '%' character.
