Information Provided by the ToolTalk Service

The ToolTalk service provides an allocation stack in the ToolTalk API library to store information it gives to you. For example, if you ask for the sessid of the default session with tt_default_session, the ToolTalk service returns the address of the character string in the allocation stack (a char * pointer) that contains the sessid. After you retrieve the sessid, you can dispose of the character string to clean up the allocation stack.

Do not confuse the API allocation stack with your program's runtime stack. The API stack will not discard information until instructed to do so.
