DTWAIN_EnumSupportedCapsEx

The DTWAIN_EnumSupportedCapsEx function returns a DTWAIN_ARRAY with all of a Source's supported capabilities.

DTWAIN_ARRAY DTWAIN_EnumSupportedCapsEx ( DTWAIN_SOURCE Source );

Parameters

Source

Specifies an open TWAIN Source.

Return Values

If the function succeeds, a DTWAIN_ARRAY is returned that contains all of the supported capabilities. If the function fails, a NULL DTWAIN_ARRAY is returned. On failure, DTWAIN_GetLastError() should be called to determine the reason for the failure.

Comments

The DTWAIN_EnumSupportedCapsEx2 function performs the same function as DTWAIN_EnumSupportedCaps (), with the difference being that the DTWAIN_ARRAY is returned instead of the program having to provide a pointer to the DTWAIN_ARRAY.

Note that the Source should be an opened Source.

TWAIN State Transitions

The source must be opened in State 4
