wiasWriteBufToFile function (wiamdef.h)

The wiasWriteBufToFile function writes from a specified buffer to an image file.

Syntax

HRESULT wiasWriteBufToFile(
       LONG                      lFlags,
  [in] PMINIDRV_TRANSFER_CONTEXT pmdtc
);

Parameters

lFlags

Specifies a set of operation flags. This parameter should be set to 0.

[in] pmdtc

Pointer to a MINIDRV_TRANSFER_CONTEXT structure.

Return value

On success, the function returns S_OK. If the function fails, it returns a standard COM error or one of the WIA_ERROR_XXX errors (described in the Microsoft Windows SDK documentation).

Remarks

A WIA minidriver uses this function to write a buffer to any type of image file. A driver that intends to write a page of purely image data to a multipage TIFF file, delegating the addition of the appropriate tags, image file directory (IFD) entries, and other nonimage data to the WIA service, should use wiasWritePageBufToFile.
