);

Arguments:
| Name | Type | Description |
| lpFileInfo | LPAT_TWAIN_FILEINFO | Pointer to an AT_TWAIN_FILEINFO structure that receives information about the first file in a directory. |
Return Value:
Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.
Supported Raster Image Formats:
This function does not process image pixels.
Remarks:
The Data Source positions the file system context to point to the first filename. lpFileInfo->szName contains the absolute path and name of the file. If the Application calls IG_TWAIN_file_get_image(), the current image will be transferred. Applications must not assume any ordering of the files delivered by the Data Source, with one exception: if IG_TWAIN_file_get_first() is called in the root directory, the operation must return an IG_TW_FY_CAMERA device.
Use IG_TWAIN_source_open() to select the desired Data Source.
