FindFirstUrlCacheEntry

Begins the enumeration of the Internet cache.

VB4-32,5,6
Declare Function FindFirstUrlCacheEntry Lib "wininet.dll" Alias "FindFirstUrlCacheEntryA" (ByVal lpszUrlSearchPattern As String, ByVal lpFirstCacheEntryInfo As Long, ByRef lpdwFirstCacheEntryInfoBufferSize As Long) As Long

Operating Systems Supported
Requires Internet Explorer 3.0

Library
Wininet

Parameter Information
lpszUrlSearchPattern
[in] Pointer to a string that contains the source name pattern to search for. This can be set to "cookie:" or "visited:" to enumerate the cookies and URL History entries in the cache. If this parameter is NULL, the function uses *.*.

lpFirstCacheEntryInfo
[out] Pointer to an INTERNET_CACHE_ENTRY_INFO structure.

lpdwFirstCacheEntryInfoBufferSize
[in, out] Pointer to an unsigned long integer variable that specifies the size of the lpFirstCacheEntryInfo buffer, in TCHARs. When the function returns, the variable contains the number of TCHARs copied to the buffer, or the required size, in bytes, needed to retrieve the cache entry.

Return Values
Returns a handle that the application can use in the FindNextUrlCacheEntry function to retrieve subsequent entries in the cache. If the function fails, the return value is NULL. To get extended error information, call GetLastError.

ERROR_INSUFFICIENT_BUFFER indicates that the size of lpFirstCacheEntryInfo as specified by lpdwFirstCacheEntryInfoBufferSize is not sufficient to contain all the information. The value returned in lpdwFirstCacheEntryInfoBufferSize indicates the buffer size necessary to contain all the information.
