* 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.
* Description : Header file of W3100A for 8051
