效果等同于ipconfig /flushdns 命令。
DnsFlushResolverCache 函数是在Dnsapi.dll导出，该函数没有任何参数。MSDN中找不到他，看来是个Undocumented函数，函数原型：
BOOL WINAPI DnsFlushResolverCache(VOID);
BOOL __stdcall DnsFlushResolverCache()
{
BOOL bRet = FALSE;
typedef BOOL (WINAPI *PfuncDnsFlushResolverCache)(VOID);
HMODULE hDnsModule = LoadLibrary( _T("dnsapi.dll") );
if ( hDnsModule != NULL )
{
PfuncDnsFlushResolverCache pFlushFun = GetProcAddress( hDnsModule, "DnsFlushResolverCache" );
if ( pFlushFun != NULL )
{
pFlushFun();
bRet = TRUE;
}
FreeLibrary( hDnsModule );
}
return bRet;
}
vb6 申明:
Private Declare Function DnsFlushResolverCache Lib "dnsapi.dll" () As Long
DnsFlushResolverCache 清除windows DNS缓存
