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.
SB_AcceptTcp
Function Waits for network connection of TCP socket handle.
Format Int SB_AcceptTcp (int Socket_No, int wait_msec);
Parameter Socket_No
wait_msec TCP socket handle number to wait for connection.
(Return value of SB_ListenTcp)
Connection standby time (in msec)
Returns -1 ~ N New handle number of connected TCP socket.
-1: Socket error
0: Waiting for connection
N: New handle number of connected TCP socket.
Notice When new handle number is given after connection is made, previous
handle that has been waiting will be closed inside this function.
SB_AcceptTcpMulti
Function Grants network multiple connection of TCP socket handle waiting for
connection.
Format Int SB_AcceptTcpMulti (int Socket_No, int wait_msec);
