Members
- dwStructSize
Unsigned long integer value that contains the size, in TCHARs, of this structure. This value can be used to help determine the version of the cache system.
- lpszSourceUrlName
Address of a string that contains the URL name. The string occupies the memory area at the end of this structure.
- lpszLocalFileName
Address of a string that contains the local file name. The string occupies the memory area at the end of this structure.
CacheEntryType
Unsigned long integer value that contains the cache type bitmask. Currently, the cache entry type value of resources from the Internet is equal to zero. For History and Cookie entries, the cache entry type is a combination of two values. One value determines how the cache entry is handled; the second value indicates what is being cached. The following table shows values that determine how the cache entry is handled.Value Description EDITED_CACHE_ENTRY
The cache entry has been altered since it was downloaded from the Internet.
NORMAL_CACHE_ENTRY
A normal cache entry, which can be deleted to recover space for new entries.
SPARSE_CACHE_ENTRY
Not currently implemented.
STICKY_CACHE_ENTRY
A sticky cache entry that is exempt from scavenging for the amount of time specified by the dwExemptDelta parameter. The default value set by the CommitUrlCacheEntry function is one day.
- dwUseCount
Unsigned long integer value that contains the current user count of the cache entry.
- dwHitRate
Unsigned long integer value that contains the number of times the cache entry was retrieved.
- dwSizeLow
Unsigned long integer value that contains the low order of the file size, in TCHARs.
- dwSizeHigh
Unsigned long integer value that contains the high-order DWORD of the file size, in TCHARs.
- LastModifiedTime
FILETIME structure that contains the last modified time of this URL, in Greenwich mean time format.
- ExpireTime
FILETIME structure that contains the expiration time of this file, in Greenwich mean time format.
- LastAccessTime
FILETIME structure that contains the last accessed time, in Greenwich mean time format. This member is not supported by a file allocation table (FAT) file system on CE.
- LastSyncTime
FILETIME structure that contains the last time the cache was synchronized.
- lpHeaderInfo
Address of a buffer that contains the header information. The buffer occupies the memory at the end of this structure.
- dwHeaderInfoSize
Unsigned long integer value that contains the size of the lpHeaderInfo buffer, in TCHARs.
- lpszFileExtension
Address of a string that contains the file extension used to retrieve the data as a file. The string occupies the memory area at the end of this structure.
- dwReserved
Reserved. Must be set to zero.
- dwExemptDelta
Unsigned long integer value that contains the exemption time, in seconds, from the last accessed time.
Remarks
There is no cache entry size limit, so applications that need to enumerate the cache must be prepared to allocate variable-sized buffers.
