This function deletes an empty directory from an installable file system. The application does not call this function directly. Instead, it uses the corresponding standard Win32 function RemoveDirectory. File System Disk Manager (FSDMGR) determines the file system type and calls the MyFSD _RemoveDirectoryWimplementation of the function.

Syntax 

BOOL MyFSD_RemoveDirectoryW( 
  PVOLUME 
pVolume,
  PCWSTR 
pwsPathName
);

Parameters

pVolume

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

pwsPathName

[in] Pointer to a null-terminated string that specifies the path of the directory to be removed. The path must specify an empty directory, and the calling process must have delete access to the directory.

Return Value

Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.

Remarks

An FSD exports this function if it supports the RemoveDirectoryfunction. 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 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 services 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 FAT file system is FATFSD_CreateDirectoryW. That is, the application calls CreateDirectory, causing FSDMGR to call FATFSD_CreateDirectoryW.
