SB_ConnectTcp
Function Make connection to the server specified as TCP socket.
Format Int SB_ConnectTcp (char *IP_Address, int Socket_No, int Wait_Sec,
Int Tx_Size, int Rx_Size);
Parameter IP_Address IP address to connect in string type
Socket_No
Wait_Sec
Tx_Size
Rx_Size
Socket number of the server to connect
Wait time for connection (in second)
Tx buffer size of the socket (in K bytes)
Rx buffer size of the socket (in K bytes)
Returns -1 ~ N Handle number of the connected socket
-1: Connection failure
N: Handle number of the connected socket
Notice If the connection is not made when this function is called, it will try to re-
connect for time specified in wait_sec and return.
Tx,Rx_Size are size of the socket buffer size. These can be set from 1 to
64.
If it is set to number smaller than 1, size will 4kbytes as default; number
larger than 64 will set size of the buffer to 64kbytes as default.
SB_ListenTcp
Function Wait for connection to TCP socket
Format Int SB_ListenTcp (int Socket_No, Int Tx_Size, int Rx_Size);
Parameter Socket_No
Tx_Bytes
Rx_Bytes
TCP socket number to wait for connection
Tx buffer size of the socket (in K bytes)
Rx buffer size of the socket (in K bytes)
Returns -1 ~ N Handle number of the TCP socket waiting for
connection
-1: Socket connection waiting failure
N: Handle number of the TCP socket waiting for
connection
Notice As a non-blocking function, this function requests connection and returns
without waiting for connection. SB_AcceptTcp will handle waiting for
connection.
Tx,Rx_Size are size of the socket buffer size. These can be set from 1 to
64.
If it is set to number smaller than 1, size will 4kbytes as default; number
larger than 64 will set size of the buffer to 64kbytes as default.
