Subject: [dpdk-dev] [PATCH 1/7] cmdline: make implementation opaque
Date: Sun, 21 Jun 2020 00:05:04 +0300 [thread overview]
Message-ID: <20200620210511.13134-2-dmitry.kozliuk@gmail.com> (raw)
In-Reply-To: <20200620210511.13134-1-dmitry.kozliuk@gmail.com>
struct cmdline exposes platform-specific members it contains, most
notably struct termios that is only available on Unix. Make the
structure opaque.
Remove tests checking struct cmdline content as meaningless.
Add cmdline_get_rdline() to access history buffer.
The new function is currently used only in tests.
