WSAStartup初始化不成功

[龙在江湖aa]

if (WSAStartup(MAKEWORD(2, 2), &wsaData) != 0)
{
/*如果初始化不成功则报错，GetLastError()返回发生的错误信息*/
printf("WSAStartup() failed: %d\n", GetLastError());
return ;
}
m_socket = INVALID_SOCKET;

WSAEACCES 10013 Permission denied. An attempt was made to access a socket in a way forbidden by its access permissions. An example is using a broadcast address for sendto without broadcast permission being set using setsockopt(SO_BROADCAST). Another possible reason for the WSAEACCES error is that when the bind function is called (on Windows NT 4.0 with SP4 and later), another application, service, or kernel mode driver is bound to the same address with exclusive access. Such exclusive access is a new feature of Windows NT 4.0 with SP4 and later, and is implemented by using the SO_EXCLUSIVEADDRUSE option.

这种问题先GetLastError看看返回值是多少
