Subject: Correctly set errno when sockets API is enabled.
X-Git-Tag: 2.7.0~149
X-Git-Url: https://codewiz.org/gitweb?a=commitdiff_plain;h=dcf825f3b1272edaea8977c82358d58fac0cb35c;p=bertos.git

Correctly set errno when sockets API is enabled.

The sockets.c provides BSD compatible sockets API, which uses errno
to communicate which error occurred.
Without setting ERRNO, it's not possible to find out which error
occurred, eg. it's not possible to understand if the peer reset the
connection after a call to send().
