windows平臺上無論利用socket()函式還是WSASocket()函式建立的socket都是阻塞模式的：[cpp] view plain copy

SOCKET WSAAPI socket(

_In_ int af,

_In_ int type,

_In_ int protocol

);

SOCKET WSASocket(

_In_ int af,

_In_ int type,

_In_ int protocol,

_In_ LPWSAPROTOCOL_INFO lpProtocolInfo,

_In_ GROUP g,

_In_ DWORD dwFlags

);
