/* SCTP kernel Implementation

*
* This file has test cases to test the accept () and close () call for

*
* accept () Tests:
* ---------------
* TEST1: Bad socket descriptor
* TEST2: Invalid socket
* TEST3: Invalid address
* TEST4: On a non-listening socket
* TEST5: On a established socket
* TEST6: On a CLOSED association
* TEST7: Extracting the association on the listening socket
*
* close () Tests:
* --------------
* TEST8: Bad socket descriptor
* TEST9: valid socket descriptor
* TEST10: Closed socket descriptor
