Comments

The DTWAIN_GetJobControl function gets the current job control type for the Source Source. The lpJobControl is the address of a LONG that will be filled in with the job control type on successful return. If bGetCurrent is TRUE, the job control type returned is the current job control type. If bGetCurrent is FALSE, the default job control type is returned. The value stored at the lpPaperSize address on return can be any one of the following Job Control Constants.

Job control is usually found on high-end scanners. To see if job control is supported for a Source, call DTWAIN_IsJobControlSupported.
