vc怎样以shared-memory的协议连接MySql数据库？

[lookmai]

my.ini已经设置好，命令行可以登陆，但在vc连接不了
[mysqld]
skip-networking
shared-memory
shared-memory-base-name=MYSQL
[client]
protocol=memory
shared-memory-base-name=MySQL

c代码，用mysql-8.0.16里面的include和lib.
mysql_init(&mysql);
if (!mysql_real_connect(&mysql, "localhost", "root", "***", "***", 0, NULL, 0))
printf("连接失败！\\n");

网上找了很多，都解决不了问题。但用tcp是可以连接的

[现在还是人类]

#include<iostream>
#include<cstdlib>
#include<string>
#include<mysql/mysql.h>
using namespace std;
MYSQL *conn;
MYSQL_RES *rs;
MYSQL_ROW fields;
int main(int argc, char *argv[])
{
	string host;
	string user;
	string pwd;
	string db_name;
	string sql;
	conn	= mysql_init(NULL);
	if(conn==NULL){
		printf("Initialization connection fail.\r\n");
		return 1;
	}
	printf("Initialization connection OK.\r\n");
	host = "127.0.0.1";
	user = "root";
	pwd = "123456";
	db_name = "testdb";
	conn = mysql_real_connect(conn, host.c_str(),user.c_str(), pwd.c_str(), db_name.c_str(), 0, NULL, 0);
	if(conn==NULL){
		printf("Connection database fail.\r\n");
		return 1;
	}
	printf("Connection database OK.\r\n");
	sql = "SELECT * FROM `users`";
	if(mysql_query(conn, sql.c_str())){
		printf("exec search fail.\r\n");
		mysql_close(conn);
		return 1;
	}
	rs = mysql_use_result(conn);
	fields = mysql_fetch_row(rs);
	printf("fields 3:%s\r\n",fields[3]);
	mysql_free_result(rs);
	mysql_close(conn);
	return 0;
}

谢谢，用socket是可以连接的，但在window本机,我想以shared-memory方式连接，性能会更高些。
