Detailed Description

Representation of a uIP TCP connection.

The uip_conn structure is used for identifying a connection. All but one field in the structure are to be considered read-only by an application. The only exception is the appstate field whose purpose is to let the application store application-specific state (e.g., file pointers) for the connection. The type of this field is configured in the "uipopt.h" header file.
