如何使用 DeleteUrlCacheEntry系列函数删除指定url缓存内存？100分
FindFirstUrlCacheEntry，FindNextUrlCacheEntry，DeleteUrlCacheEntry用这系列函数怎么删除指定的比如‘http://baidu.com’这网址相关的缓存？ 求代码示例

[解决办法]
自己多查查MSDN吧，上面的参数说明很全的，我刚刚看过了，都是比较简单的入参。
提供一个清空IE缓存的例子

C/C++ code

void ClearInternetCache() { DWORD dwNeeded = 0; FindFirstUrlCacheEntry(NULL, NULL, &dwNeeded); if (GetLastError() == ERROR_INSUFFICIENT_BUFFER) { unsigned char *buffer = new unsigned char[dwNeeded]; try { LPINTERNET_CACHE_ENTRY_INFO lpicei = reinterpret_cast(buffer); HANDLE HFind = FindFirstUrlCacheEntry(NULL, lpicei, &dwNeeded); DeleteUrlCacheEntry(lpicei->lpszSourceUrlName); bool no_more_files = false; while (!no_more_files) { if (FindNextUrlCacheEntry(HFind, lpicei, &dwNeeded)) { DeleteUrlCacheEntry(lpicei->lpszSourceUrlName); } else switch (GetLastError()) { case ERROR_INSUFFICIENT_BUFFER: { delete [] buffer; buffer = new unsigned char[dwNeeded]; lpicei = reinterpret_cast(buffer); break; } default: { no_more_files = true; break; } } }FindCloseUrlCache(HFind);} catch (...) { delete [] buffer; } delete [] buffer; } }
