An application initializes the stack before performing any other tasks. The initialization parameters can be broadly subdivided into the following four types:
Generic stack parameters
Upper layer registrations
Connection manager interfaces
Custom header table
After initializing the stack, an application creates requests by using the interfaces that are provided by the header management layer. Applications send requests by using the message formatting layer's interface. Applications receive incoming requests and responses after initializing the stack and pass the requests and responses to the stack for processing.
