This function copies the content of a source file to a destination file in an installable file system and deletes the source file. The application does not call this function directly. Instead, it uses the corresponding standard Win32 function DeleteAndRenameFile. The File System Disk Manager (FSDMGR) determines the file system type and calls the MyFSD _DeleteAndRenameFileWimplementation of the function.

Syntax 

BOOL MyFSD_DeleteAndRenameFileW( 
  PVOLUME 
pVolume,
  LPCWSTR 
lpszDestFileName,
  LPCWSTR 
lpszSourceFileName
);

Parameters

pVolume

[in] Pointer to the value that a file system driver (FSD) defines in its DLL and passes to the FSDMGR_RegisterVolumefunction when registering the volume. The definition of this parameter can point to private structures.

lpszDestFileName

[in] Pointer to a null-terminated string that contains the path of the destination file. This parameter cannot be set to NULL.

lpszSourceFileName

[in] Pointer to a null-terminated string that contains the path of the source file. This parameter cannot be set to NULL.

Return Value

TRUE indicates success. FALSE indicates failure. For extended error information, call GetLastError.

Remarks

An FSD exports this function if it supports DeleteAndRenameFile. All FSD functions can be called on re-entry. Therefore, take this into account when developing an FSD.

FSDMGR is a DLL that manages all OS interaction with installable files systems. Each installable file system requires an FSD, which is a DLL that supports 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, its DLL is MyFSD.dll, and its exported functions are prefaced with MyFSD_*.

FSDMGR provides service functions to FSDs. The FSDMGR_RegisterVolume, the FSDMGR_CreateFileHandle, and the FSDMGR_CreateSearchHandlefunctions record a DWORDof volume-specific data that an FSD associates 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 creates a folder on a device that contains an installable file system, it calls the CreateDirectoryfunction. 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.
