DTWAIN_EnumExtendedCapsEx

The DTWAIN_EnumExtendedCapsEx function fills a DTWAIN_ARRAY with all of a Source's supported extended device capabilities.

DTWAIN_ARRAY DTWAIN_EnumExtendedCapsEx ( DTWAIN_SOURCE Source );

Parameters

Source

An open TWAIN Source.

Return Values

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

Comments

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