Subject: [PATCH v5 1/6] strbuf: add shortcut to work with error messages
Date: Wed, 21 Mar 2018 18:28:49 +0000
Message-ID: <0102016249d21c40-0edf6647-4d26-46fc-8cfd-5a446b93a5e2-000000@eu-west-1.amazonses.com> (raw)
In-Reply-To: <01020162442818b4-c153f9ce-3813-41a6-aebd-f5cb2b98b1fa-000000@eu-west-1.amazonses.com>

Add function strbuf_error() that helps to save few lines of code.
Function expands fmt with placeholders, append resulting error message
to strbuf *err, and return error code ret.
