This function continues a file search from a previous call to the MyFSD_FindFirstFileWfunction. The application does not call this function directly. Instead, it uses the corresponding standard Win32 function FindNextFile. The File System Disk Manager (FSDMGR) determines the file system type and calls the MyFSD_ FindNextFileWimplementation of the function.

Syntax 

BOOL MyFSD_FindNextFileW( 
  PSEARCH 
pSearch, 
  PWIN32_FIND_DATAW 
pfd
);

Parameters

pSearch

[in] Pointer to the value that a file system driver (FSD) passes to the FSDMGR_CreateSearchHandlefunction that creates the search handle.

pfd

[out] Pointer to a WIN32_FIND_DATAstructure that receives information about the found file or subdirectory. The structure can be used in subsequent calls to MyFSD_ FindNextFileWto refer to the file or directory.

Return Value

Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError. If no matching files can be found, the GetLastErrorfunction returns ERROR_NO_MORE_FILES.

Remarks

This function searches for files by name only. It cannot be used for attribute-based searches.

An FSD exports this function, if it supports FindNextFile. 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 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.
