开发完成端口。WSAID_ACCEPTEX 怎么定义啊？

[wulengbing]

VC中可以这样定义
#define WSAID_ACCEPTEX \
{0xb5367df1,0xcbac,0x11cf,{0x95,0xca,0x00,0x80,0x5f,0x48,0xa1,0x92}}

在d中我这样定义为什么出错啊？
const
WSAID_ACCEPTEX: TGUID = '($b5367df1; $cbac; $11cf; ($95, $ca, $00, $80, $5f, $48, $a1, $92))';

请高手指教，应该怎么定义这个TGUID?

[wulengbing]

那在那儿下载正确的Winsock2.pas啊？
问题还没有解决啊？

[wulengbing]

我是在http://jungla.dit.upm.es/~bti/files/winsock2.pas下载的啊。

const
WSAID_ACCEPTEX: TGUID = (D1:$b5367df1; D2:$cbac; D3:$11cf; D4:($95, $ca, $00, $80, $5f, $48, $a1, $92));
type
LPACCEPTEX = function(sListenSocket: TSocket; sAcceptSocket: TSocket; lpOutputBuffer: Pointer;
dwReceiveDataLength: DWORD; dwLocalAddressLength: DWORD; dwRemoteAddressLength: DWORD;
lpdwBytesReceived: PDWORD; lpOverlapped: POverlapped): BOOL; stdcall;
TAcceptEx = LPACCEPTEX;

function WSAGetExtensionFunctionPointer(s: TSocket; const gdExFuncGuid: TGUID): Pointer;

[僵哥]

const
WSAID_ACCEPTEX: TGUID = (Data1:$b5367df1; Data2:$cbac; Data3:$11cf; Data4:($95, $ca, $00, $80, $5f, $48, $a1, $92));
type
LPACCEPTEX = function(sListenSocket: TSocket; sAcceptSocket: TSocket; lpOutputBuffer: Pointer;
dwReceiveDataLength: DWORD; dwLocalAddressLength: DWORD; dwRemoteAddressLength: DWORD;
lpdwBytesReceived: PDWORD; lpOverlapped: POverlapped): BOOL; stdcall;
TAcceptEx = LPACCEPTEX;

function WSAGetExtensionFunctionPointer(s: TSocket; const gdExFuncGuid: TGUID): Pointer;

基础知识吧。。。

[wulengbing]

WSAID_ACCEPTEX: TGUID = (Data1:$b5367df1; Data2:$cbac; Data3:$11cf; Data4:($95, $ca, $00, $80, $5f, $48, $a1, $92));

在$00怎么这里会报类型不匹配啊？'Char' and 'Integer'
请高手解决啊。

winsock2中TGUID的定义
u_char:Char;

PGUID = ^TGUID;
TGUID = packed record
Data1 :u_long;
Data2 :u_short;
Data3 :u_short;
Data4 : array [0..8-1] of u_char;
end;

//Data4定义的是char数组不是byte数组
const
WSAID_ACCEPTEX: TGUID = (Data1:$b5367df1; Data2:$cbac; Data3:$11cf; Data4:(char($95), char($ca), char($00), char($80), char($5f), char($48), char($a1), char($92)));

[hongqi162]

const
WSAID_ACCEPTEX: TGUID = (
D1:$b5367df1; D2:$cbac; D3:$11cf; D4:($95, $ca, $00, $80, $5f, $48, $a1, $92));

[constantine]

WSAID_ACCEPTEX: TGUID = '{b5367df1-cbac-11cf-95ca-00805f48a192}';
这样也可以吧

楼主拿到的Winsock2这个pas文件当中对TGUID定义有问题。

哈哈，这几天我也在弄IOCP的东西，现在可以测试了，不过本机ECHO有问题，我拿一个现成的应用客户端（也就是Windows Platform当中的那个IOCPClient)，发送接收受发送缓冲区1024倍的数据，由于发送端不支持重叠IO，而我设置成支持重叠IO，结果对方发送的源源不断，但是不接受，从而导致发送端内存猛涨。之前就更加离谱，我使用每一数据包，一次发送，结果整个本机的网络都挂了（内核驱动内存耗尽）。
