MAX_LINGER_SECONDS定义在哪里 [英] Where is MAX_LINGER_SECONDS definition

问题描述

亲爱的，

我曾尝试关闭套接字，但是VC编译器报告错误消息错误C2065:"MAX_LINGER_SECONDS":未声明的标识符".
您能让我知道必须包含哪个头文件吗?

Dear,

I was try close socket but VC compiler report error message "error C2065: ''MAX_LINGER_SECONDS'' : undeclared identifier".
Would you let me know, which header file have to include?

void CFtpc::CloseSocket( SOCKET *socket )
{
	fd_set				read_fds;
	fd_set				error_fds;
	struct timeval		t_timeout;
	if( *socket != INVALID_SOCKET )
	{
		if( shutdown( *socket, SD_BOTH ) != SOCKET_ERROR )
		{
			FD_ZERO( &read_fds );
			FD_ZERO( &error_fds );
			FD_SET( *socket, &read_fds );
			FD_SET( *socket, &error_fds );
			t_timeout.tv_sec = MAX_LINGER_SECONDS;
			t_timeout.tv_usec = 0;
			select( 1, &read_fds, NULL, &error_fds, &t_timeout );
		}
		closesocket( *socket );
		*socket = INVALID_SOCKET;
	}
}

推荐答案

找不到任何这样的东西.
也许是自定义的常量.
您可以使用#define自己定义.

Didn''t find any such thing.
Maybe its a custom defined constant.
You could define it yourself using #define.

该值是应用程序特定的值，因此不能在通用标头中声明.遵循超人的建议并自己定义.

That value is an application specific value, and therefor cannot be declared in a common header. Follow supermans suggestion and define it yourself.
