2 SPI Procedures and Functions
SPI Procedure Calls
Both SPI requesters and servers use SPI procedures to initialize messages and
extensible structured tokens, place tokens in messages, retrieve token values from
messages, and move tokens from one message buffer to another. The general syntax
follows the description of each procedure.

This procedures initializes a SPI buffer with an appropriate header and places values
in header fields.
