DTWAIN_IsFileXferSupported

The DTWAIN_IsFileXferSupported function checks if a Source supports file transfers.

DTWAIN_BOOL DTWAIN_IsFileXferSupported (

DTWAIN_SOURCE	Source,
DTWAIN_LONG	FileType );

Parameters

Source

Specifies an open TWAIN Source.

FileType

Specifies a TWAIN File Type, or DTWAIN_ANYSUPPORT.

Return Values

If file transfers are supported for the given file type by the Source, TRUE is returned. Otherwise FALSE is returned.

Comments

The DTWAIN_IsFileXferSupported function takes the open Source Source, and checks to see if the file type FileType, is supported when DTWAIN attempts a file transfer using the Source's internal file transfer support. The FileType can be any one of the following types defined in :DTWAIN File Transfer Constants. If FileType is DTWAIN_ANYSUPPORT, DTWAIN_IsFileXferSupported returns whether the Source supports any file transfers.

Note: Many Source's do not support file transfers, thereby DTWAIN_IsFileXferSupported will always return FALSE for these Sources.

TWAIN State Transitions

The source must be opened in State 4
