This function sends an I/O control to a file system driver (FSD). It may not be supported by all file system drivers, and not all implementations support all I/O controls.
Syntax
BOOL CeFsIoControl(
LPCWSTR pszDir,
DWORD dwIoControlCode,
LPVOID lpInBuffer,
DWORD nInBufferSize,
LPVOID lpOutBuffer,
DWORD nOutBufferSize,
LPDWORD lpBytesReturned,
LPOVERLAPPED lpOverlapped
);
Parameters
- pszDir
[in] String representing the system mount point. Set to NULL to access the object store file system.
- dwIoControlCode
[in] File system I/O control code.
- lpInBuffer
[in] Long pointer to a buffer that contains the data required to perform the operation. Set to NULL if the dwIoControlCode parameter specifies an operation that does not require input data.
- nInBufferSize
[in] Size, in bytes, of the buffer pointed to by lpInBuffer.
- lpOutBuffer
[out] Long pointer to a buffer that receives the output data for the operation. Set to NULL if dwIoControlCode does not produce output data.
- nOutBufferSize
[in] Size, in bytes, of the buffer pointed to by lpOutBuffer.
- lpBytesReturned
[out] Long pointer to a variable that receives the size, in bytes, of the data stored in the buffer pointed to by lpOutBuffer.
- lpOverlapped
[in] Ignored. Set to NULL.
Return Value
TRUE indicates success. FALSE indicates failure. If this function is not supported by an FSD, it returns FALSE, and GetLastError returns ERROR_NOT_SUPPORTED.
