ScanSourceStatusEnum enumeration constants are used to define the current status of scanning source.

typedef enum {


Name Description
SS_Disconnected The scanning source is disconnected and therefore not available for processing.

The scanning source is idle and can be used at once.

Note: Scanners with TWAIN scanning API may return this status even if the scanning source is only registered. If you try to use the scanner which is registered but not connected, an error will occur. However, note that some scanners with TWAIN scanning API can make an attempt to scan with unconnected source and only after that return the connection error.

SS_Busy The scanning source is currently performing a scanning operation. It will be possible to use it after the operation is completed.
