This function gets the next filename in a directory, and returns information about that file (the same information that can be retrieved with IG_TWAIN_file_info_get()).
Declaration:

|---|---|
AT_ERRCOUNT ACCUAPI IG_TWAIN_file_get_next(
LPAT_TWAIN_FILEINFO lpFileInfo);
|
|
Arguments:
| lpFileInfo | Pointer to an AT_TWAIN_FILEINFO structure that receives information about the next 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 next 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. A call to IG_TWAIN_file_get_first() must be issued on a given directory before the first call to IG_TWAIN_file_get_next().
