Subject: [PATCH v3 2/3] testpmd: use sig_atomic_t for flag
Date: Tue, 14 Mar 2023 10:36:47 -0700 [thread overview]
Message-ID: <20230314173648.69528-3-stephen@networkplumber.org> (raw)
In-Reply-To: <20230314173648.69528-1-stephen@networkplumber.org>
Standard conforming signal handling in applications should use sig_atomic_t
for flags set by signal handler.
https://www.gnu.org/software/libc/manual/html_node/Atomic-Data-Access.html
This is really just a fancy way of saying ''int'' but adds
to platform portablilty for DPDK.
