Subject: [PATCH v2 01/11] strbuf: introduce strbuf_split_str_without_term()
Date: Wed, 16 Dec 2015 20:59:52 +0530 [thread overview]
Message-ID: <1450279802-29414-2-git-send-email-Karthik.188@gmail.com> (raw)
In-Reply-To: <1450279802-29414-1-git-send-email-Karthik.188@gmail.com>
The current implementation of 'strbuf_split_buf()' includes the
terminator at the end of each strbuf post splitting. Add an option
wherein we can drop the terminator if desired. In this context
introduce a wrapper function 'strbuf_split_str_without_term()' which
splits a given string into strbufs without including the terminator.
