DTWAIN_EnumCamerasEx

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

DTWAIN_ARRAY DTWAIN_EnumCamerasEx ( DTWAIN_SOURCE Source );

Parameters

Source

An open TWAIN Source.

Return Values

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

Comments

The DTWAIN_EnumCamerasEx function has the same functionality as DTWAIN_EnumCameras, 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
