网络编程中 SOCKET Accept=SOCKET_ERROR 编译的时候报错

SOCKET Accept=(SOCKET) SOCKET_ERROR

加个转换就好模绝弊了

-1只是个警告，没关系的 后面报警宏携搞得地方都可以强制转旦族换

你要添加相关头文件顷吵 和库雀棚侍

#include <winsock2.h>

#pragma comment(lib,"Ws2_32.lib")

希望对你有所和运帮助

#include <iostream>

#include <stdio.h>

#include "/home/mysql/include/mysql.h"

int main()

{

MYSQL mysql

MYSQL_RES *result=NULL

MYSQL_FIELD *field=NULL

mysql_init(&mysql)

mysql_real_connect(&mysql, "弯陪激厅localhost", "root", "neusoft", "test", 3306, NULL, 0)

// string sql = "create table a1(col int)"

// mysql_query(&mysql,"insert into a values(3)")

mysql_query(&mysql,"select col from a")

result=mysql_store_result(&mysql)

int fieldcount = mysql_num_fields(result)

MYSQL_ROW row

row = mysql_fetch_row(result)

while(NULL != row)

{

for(int i=0i<fieldcounti++)

{

//field=mysql_fetch_field_direct(result,i)

//printf("%s",row[i])

std::cout<<row[i]<<std::endl

}

//std::cout<<std::endl

row = mysql_fetch_row(result)

}

//mysql_query(&mysql,sql.c_str())

mysql_close(&mysql)

}

这是我埋铅蠢成功 *** 作的代码。。。。。
