MyFSD_SetFileTime (Windows CE 5.0)
This function sets the date and time that a file in an installable file system was created, last accessed, or last modified. The application does not call this function directly. Instead, use the corresponding standard Win32 function SetFileTime. The FSD Manager determines the file system type and calls the MyFSD_SetFileTime implementation of the function.
BOOLMyFSD_SetFileTime( PFILEpFile,CONSTFILETIME*pCreation, CONSTFILETIME* pLastAccess, CONSTFILETIME* pLastWrite );
Parameters
- pFile
[in] Pointer to the value that an FSD passes to the FSDMGR_CreateFileHandle function when creating the file handle. - pCreation
[in] Pointer to a FILETIME structure that contains the date and time the file was created. This parameter can be NULL, if the application does not need to set this information. - pLastAccess
[in] Pointer to a FILETIME structure that contains the date and time the file was last accessed. The last access time includes the last time the file was written to, read from, or, in the case of executable files, run. This parameter can be NULL, if the application does not need to set this information. - pLastWrite
[in] Pointer to a FILETIME structure that contains the date and time the file was last written to. This parameter can be NULL, if the application does not want to set this information.
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 SetFileTime 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 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 services to FSDs. The FSDMGR_RegisterVolume, FSDMGR_CreateFileHandle, and FSDMGR_CreateSearchHandle functions record a DWORD of volume-specific data the 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 FAT file system is FATFSD_CreateDirectoryW. That is, the application calls CreateDirectory, causing Fsdmgr to call FATFSD_CreateDirectoryW.
The FAT and NTFS file systems support the file creation, last access, and last write-time values.
