Interface) The programming interface for developing Windows drivers under WOSA. In order to provide common access to services, the application (query, word processor, email program, etc.) is written to a particular WOSA-supported interface, such as ODBC or MAPI, and the developer of the service software (database manager, document manager, print spooler, etc.) writes to the SPI for that class of service.
