Message Streaming Functions

This section contains descriptions of functions that the FM can use to access the contents of the request message and to build a corresponding reply message.

Each command that is sent to the FM has a token associated with it that links to the request and reply buffers.

These functions read the request and write the response using a stream model. This scheme can improve performance by providing lower latency compared to a scheme that waits until all the request is available before starting processing.

The Message Streaming section contains the following functions:

>SVC_IO_Read

>SVC_IO_Write

>SVC_IO_GetReadPointer

>SVC_IO_GetReadBuffer

>SVC_IO_UpdateReadPointer

>SVC_IO_GetWritePointer

>SVC_IO_GetWriteBuffer

>SVC_IO_UpdateWritePointer
