| wiasFreePropContext The wiasFreePropContext function releases the memory occupied by a WIA_PROPERTY_CONTEXT structure. |
| wiasGetChangedValueFloat The wiasGetChangedValueFloat function determines whether a property with a floating-point value has been changed by an application. |
| wiasGetChangedValueGuid The wiasGetChangedValueGuid function determines whether a property with a GUID value has been changed by an application. |

| wiasGetChangedValueStr The wiasGetChangedValueStr function determines whether a property with a string value has been changed by an application. |
| wiasGetChildrenContexts The wiasGetChildrenContexts function retrieves an array of item contexts belonging to the current item's children. |
| wiasGetContextFromName The wiasGetContextFromName function retrieves the item context for an item name. |
| wiasGetDrvItem The wiasGetDrvItem function retrieves a driver item. |
| wiasGetImageInformation The wiasGetImageInformation function retrieves transfer context information from an item. |
| wiasGetItemType The wiasGetItemType function indicates the item type. |
| wiasGetPropertyAttributes The wiasGetPropertyAttributes function retrieves the access flags and valid values for a set of properties. |
| wiasGetRootItem The wiasGetRootItem function retrieves the root item context of a specified WIA item. |
| wiasIsPropChanged The wiasIsPropChanged function tests whether a specified property has been changed by an application. |

| wiasReadPropGuid The wiasReadPropGuid function retrieves a GUID property value from a WIA item. |
| wiasReadPropLong The wiasReadPropLong function retrieves a long integer property value from a WIA item. |
| wiasReadPropStr The wiasReadPropStr function retrieves a string property value from a WIA item. |
| wiasSendEndOfPage The wiasSendEndOfPage function calls the client callback routine during a data transfer, sending the current total page count. |
| wiasSetItemPropAttribs The wiasSetItemPropAttribs function sets the access flags and valid values for an item's set of properties. |
| wiasSetItemPropNames The wiasSetItemPropNames function writes property names to item properties. |
