DTWAIN_EnumTopCamerasEx

The DTWAIN_EnumTopCamerasEx function gets all of the top "cameras" that are available for the current Source. The Source must support TWAIN File System handling.

DTWAIN_ARRAY DTWAIN_EnumTopCamerasEx ( DTWAIN_SOURCE Source );

Parameters

Source

An open TWAIN Source.

Return Values

If successful, a DTWAIN_ARRAY that will store the Source's top camera names. NULL is returned on failure. If the function fails, call DTWAIN_GetLastError() to get extended information.

Comments

The DTWAIN_EnumTopCamerasEx function has the same functionality as DTWAIN_EnumTopCameras, except that the DTWAIN_ARRAY is returned to the caller instead of the caller providing a pointer to a DTWAIN_ARRAY as a parameter.

TWAIN State Transitions

The Source must be in State 4 or higher
