FindFirstUrlCacheGroup function

Initiates the enumeration of the cache groups in the Internet cache.

Syntax


HANDLE FindFirstUrlCacheGroup(
  _Reserved_ DWORD   dwFlags,
  _In_       DWORD   dwFilter,
  _Reserved_ LPVOID  lpSearchCondition,
  _Reserved_ DWORD   dwSearchCondition,
  _Out_      GROUPID *lpGroupId,
  _Reserved_ LPVOID  lpReserved
);

Parameters

dwFlags [in]

This parameter is reserved and must be 0.

dwFilter [in]

Filters to be used. This parameter can be zero or one of the following values.

ValueMeaning
CACHEGROUP_SEARCH_ALL

Search all cache groups.

CACHEGROUP_SEARCH_BYURL

Not currently implemented.

 

lpSearchCondition [in]

This parameter is reserved and must be NULL.

dwSearchCondition [in]

This parameter is reserved and must be 0.

lpGroupId [out]

Pointer to the ID of the first cache group that matches the search criteria.

lpReserved [in, out]

This parameter is reserved and must be NULL.

Return value

Returns a valid handle to the first item in the enumeration if successful, or NULL otherwise. To get specific error information, call GetLastError. If the function finds no matching files, GetLastError returns ERROR_NO_MORE_FILES.

Remarks

The handle returned from FindFirstUrlCacheGroup is used in subsequent calls to FindNextUrlCacheGroup. At the end of the enumeration, the application should call FindCloseUrlCache.

Like all other aspects of the WinINet API, this function cannot be safely called from within DllMain or the constructors and destructors of global objects.

Note  WinINet does not support server implementations. In addition, it should not be used from a service. For server implementations or services use Microsoft Windows HTTP Services (WinHTTP).
