Allocating Memory for ADSP

To open and maintain an ADSP session, you must allocate memory required for the session. Depending on the ADSP routine that you call, you must allocate the following:

• storage of the state information that ADSP maintains at either end of a connection (see the discussion of the connection control block in "Connections, Connection Ends, and Connection States" on page 5-6)
• a parameter block that you use to pass parameters when you execute an ADSP routine
• a send queue and a receive queue
• an attention message buffer

This memory belongs to ADSP until you explicitly remove the connection end.
