/**
 * The NtFsControlFile function sends a control code directly to a file system or filter driver, causing the corresponding driver to perform the specified action.
 *
 * \param[in] FileHandle A handle to the file object representing the file or directory on which the specified action is to be performed.
 * \param[in] Event A handle for a caller-created event. This parameter is optional and can be NULL. It must be NULL if the caller will wait for the FileHandle to be set to the Signaled state.
 * \param[in] ApcRoutine Address of a caller-supplied APC routine to be called when the requested operation completes. This parameter is optional and can be NULL.
 * \param[in] ApcContext Pointer to a caller-determined context area. This parameter value is used as the APC context if the caller supplies an APC, or is used as the completion context if an I/O completion object has been associated with the file object. 
 * \param[out] IoStatusBlock Pointer to an IO_STATUS_BLOCK structure that receives the final completion status and information about the operation.
 * \param[in] FsControlCode FSCTL_XXX code that indicates which file system control operation is to be carried out.
 * \param[in] InputBuffer Pointer to a caller-allocated input buffer that contains device-specific information to be given to the target driver.
 * \param[in] InputBufferLength Size, in bytes, of the buffer at InputBuffer. This value is ignored if InputBuffer is NULL.
 * \param[out] OutputBuffer Pointer to a caller-allocated output buffer in which information is returned from the target driver.
 * \param[in] OutputBufferLength Size, in bytes, of the buffer at OutputBuffer. This value is ignored if OutputBuffer is NULL.
 * \return NTSTATUS Successful or errant status.
