Commit Message

Geliang Tang July 9, 2024, 9:16 a.m. UTC 
From: Geliang Tang <tanggeliang@kylinos.cn>

This patch uses the new helper connect_fd_to_addr_str() in make_client()
instead of using local defined function make_socket() + connect(). This
local function can be dropped latter.

A new parameter "expect_errno" is added for make_client() too to allow
different "expect_errno" is passed to make_client(). It is used to check
with "errno" after invoking connect_fd_to_addr_str().
