* 
* (c) Copyright 2002, Wiznet, Seoul, Korea 
* 
* Filename : socket.h 
* Version  : 2.2 
* Programmer(s):  
* Created : 2002/01/ 
* Modified      : 2002/06/20 - added delay in initseqnum() function 
		               to complete write operation of TX Pointer Registers. 
		  2002/09/27 - Global Interrupt Status Variable & MACRO Renaming 
				      S_STATUS[] --> I_STATUS[] 
				      INT_STATUS --> INT_REG 
				      STATUS(i) --> INT_STATUS(i) 
				      C_STATUS(i) --> SOCK_STATUS(i) 
		   	     - When you read UDP or IP RAW Header at recvfrom() function, Verify Rx_Pointer Wrap-off 
			     - At close() function, Modify "while(S_STATUS[s] !=  SCLOSED)" statement to while(!(S_STATUS[s] & SCLOSED)). 
			     - At sendto()function, Checke previous send command before destination update 
                                                    Error handling 
                             - At select() and recvfrom() function,   
                                       Received UDP data process is modified 'packet size' to 'bulk size' 
		  2002/10/20 - Version Up 
			     - At select() function, 
                                       Modify to caculate free buffer size at UDP,IP_RAW protocol 
			     - Move GetDestAddr() function to 'sockutil.h' 
		  2002/10/28 - Version Up 
			     - At select(), integrated each received size caculation of TCP, UDP or IP_RAW into one calculation. 
			     - At recvfrom(), Received data is processed by packet unit.
