FindNextUrlCacheEntryW function (wininet.h)

  • Article

Retrieves the next entry in the Internet cache.

Syntax

BOOL FindNextUrlCacheEntryW(
  [in]      HANDLE                       hEnumHandle,
  [out]     LPINTERNET_CACHE_ENTRY_INFOW lpNextCacheEntryInfo,
  [in, out] LPDWORD                      lpcbCacheEntryInfo
);

Parameters

[in] hEnumHandle

Handle to the enumeration obtained from a previous call to FindFirstUrlCacheEntry.

[out] lpNextCacheEntryInfo

Pointer to an INTERNET_CACHE_ENTRY_INFO structure that receives information about the cache entry.

[in, out] lpcbCacheEntryInfo

Pointer to a variable that specifies the size of the lpNextCacheEntryInfo buffer, in bytes. When the function returns, the variable contains the number of bytes copied to the buffer, or the size of the buffer required to retrieve the cache entry, in bytes.

Return value

Returns TRUE if successful, or FALSE otherwise. To get extended error information, call GetLastError. Possible error values include the following.

Return code Description
ERROR_INSUFFICIENT_BUFFER
 The size of lpNextCacheEntryInfo as specified by lpdwNextCacheEntryInfoBufferSize is not sufficient to contain all the information. The value returned in lpdwNextCacheEntryInfoBufferSize indicates the buffer size necessary to contain all the information.
ERROR_NO_MORE_ITEMS
 The enumeration completed.

Remarks

Continue to call FindNextUrlCacheEntry until the last item in the cache is returned.

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).
 

Note

The wininet.h header defines FindNextUrlCacheEntry as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
