Subject: [PATCH 1/3] eal/windows: translate Windows errors to errno-style errors
Date: Fri,  1 Apr 2022 06:29:51 -0700	[thread overview]
Message-ID: <1648819793-18948-2-git-send-email-roretzla@linux.microsoft.com> (raw)
In-Reply-To: <1648819793-18948-1-git-send-email-roretzla@linux.microsoft.com>

Add function to translate Windows error codes to errno-style error
codes. The possible return values are chosen so that we have as
much semantical compatibility between platforms as possible.
