pulSequence [out]

The ordinal position of the parameter in the method argument list.

szName [out]

A buffer to hold the name of the parameter.

cchName [in]

The requested size in wide characters of szName.

pchName [out]

The returned size in wide characters of szName.

pdwAttr [out]

A pointer to any attribute flags associated with the parameter.

pdwCPlusTypeFlag [out]

A pointer to a flag specifying that the parameter is a ValueType.

ppValue [out]

A pointer to a constant string returned by the parameter.
