|
|
Representation of a uIP TCP connection.
|
||
|
|
<p>
|
||
|
|
The <a class="el" href="a00088.html">uip_conn</a> 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 whos 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.
