MyFSD_FindClose (Windows CE 5.0)
This function closes the specified search handle. The MyFSD_FindFirstFileW and MyFSD_FindNextFileW functions use the search handle to locate files with names that match a specified name. The application does not call this function directly. Instead, use the corresponding standard Win32 function FindClose. The FSD Manager determines the file system type and calls the MyFSD_FindClose implementation of the function.
BOOLMyFSD_FindClose( PSEARCHpSearch);
Parameters
- pSearch
[in] Pointer to the value that an FSD passes to the FSDMGR_CreateSearchHandle function when creating the search handle.
Return Values
Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.
Remarks
An FSD exports this function, if it wants to support the FindClose function. All FSD functions can be called on re-entry; therefore, FSD developers must take this into account when developing an FSD.
The Fsdmgr component is a DLL that manages all OS interaction with installable files systems. Each installable file system requires an FSD, which is a DLL that exports an API needed to support an installable file system. The name of the DLL for an FSD and the names of the functions it exports start with the name of the associated installable file system. For example, if the name of file system is MyFSD, then its DLL is MyFSD.dll and its exported functions are prefaced with MyFSD_*.
Fsdmgr provides service functions to FSDs. The FSDMGR_RegisterVolume, FSDMGR_CreateFileHandle, and FSDMGR_CreateSearchHandle functions record a DWORD of volume-specific data an FSD needs to keep associated with volume. This volume-specific data is passed as the first parameter of these three functions.
Applications that access an installable file system use standard Win32 functions. For example, when an application wants to create a folder on a device that contains an installable file system, it calls CreateDirectory. Fsdmgr recognizes that the path is to a device containing an installable file system and calls the appropriate function, which in the case of the MyFSD file system is MyFSD_CreateDirectoryW. That is, the application calls CreateDirectory, causing Fsdmgr to call **MyFSD_CreateDirectoryW.
After the **MyFSD_FindClose function is called, the handle specified by the hFindFile parameter cannot be used in subsequent calls to either the MyFSD_FindNextFileW or **MyFSD_FindClose function.
