***请问用win32api怎么实现arp -s的功能***

[wqedsaa1]

也就是不用批处理用程序直接实现这个外部命令
不是类似winexec(...)

绑定mac地址?

[bager]

Use CreateIpNetEntry of IP Helper API

The CreateIpNetEntry function creates an Address Resolution Protocol (ARP) entry in the ARP table on the local computer.

DWORD CreateIpNetEntry(
PMIB_IPNETROW pArpEntry
);

iphlpapi里面有，自己去找吧

就是想绑定mac地址啊，我是新手谁能句个例子吗
比如这个命令 arp -s 192.168.0.1 00-20-12-27-ba-c2

BOOL CDOSDlg::ExecDosCmd()
{
#define EXECDOSCMD "net send sever test?" //可以换成你的命令

SECURITY_ATTRIBUTES sa;
HANDLE hRead,hWrite;

sa.nLength = sizeof(SECURITY_ATTRIBUTES);
sa.lpSecurityDescriptor = NULL;
sa.bInheritHandle = TRUE;
if (!CreatePipe(&hRead,&hWrite,&sa,0))
{
return FALSE;
}

STARTUPINFO si;
PROCESS_INFORMATION pi;
si.cb = sizeof(STARTUPINFO);
GetStartupInfo(&si);
si.hStdError = hWrite;
si.hStdOutput = hWrite;
si.wShowWindow = SW_HIDE;
si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
//关键步骤，CreateProcess函数参数意义请查阅MSDN
if (!CreateProcess(NULL, EXECDOSCMD
,NULL,NULL,TRUE,NULL,NULL,NULL,&si,&pi))
{
return FALSE;
}
CloseHandle(hWrite);

char buffer[4096] = {0};
DWORD bytesRead;
while (true)
{
if (ReadFile(hRead,buffer,4095,&bytesRead,NULL) == NULL)
break;
//buffer中就是执行的结果，可以保存到文本，也可以直接输出
TRACE(buffer);
Sleep(200);
}
return TRUE;
}

模拟执行DOS命令，比较牵强的方法。
