This function is called by File System Disk Manager (FSDMGR) to create a new directory in an installable file system. The application originally calls the corresponding standard Win32 function CreateDirectory. This function is exported by an implementation of a file system driver (FSD) and is called indirectly by FSDMGR.

Syntax

BOOL MyFSD_CreateDirectoryW( 
  PVOLUME pVolume, 
  PCWSTR pwsPathName, 
  PSECURITY_ATTRIBUTES pSecurityAttributes
);

Parameters

  • pVolume
    [in] Pointer to the value that the FSD defines in its DLL and passes to the FSDMGR_RegisterVolume function 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 created.
  • pSecurityAttributes
    [in] Ignored. Set to NULL.

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 CreateDirectory function. 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_CreateSearchHandle functions record a DWORD of 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 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.
