我写了这样的测试程序
Action()
{
        int rc;

    rc=lrs_create_socket("socket1", "TCP",
                         "RemoteHost=10.1.2.1.107:1080", LrsLastArg);
   
    if (rc==0)

       lr_output_message("Socket1 was successfully create ");

else

       lr_output_message("An error occurred while create the socket, Error Code: %d", rc);


}
运行时出现一下错误
Action.c (6): undeclared identifier `LrsLastArg'
d:\\teststudy\\lrtestwinsocket2\\\\combined_lrtestwinsocket2.c (5): 1 errors, not writing pre_cci.ci

我不太明白LrsLastArg如何使用，

丢了头文件？

需要加什么头文件啊

#include "lrs.h"
