Sets the specified socket option. TCP supports a number of socket options. Please refer to TCP documentation for a description of these options.
Return type: LOGICAL
Applies to: Socket object handle
The following table describes the options ABL supports.
Option | Description |
---|---|
TCP-NODELAY | An enable indicator, which is either TRUE or FALSE. |
SO-LINGER | Two comma separated values:
|
SO-KEEPALIVE | Sets the TCP socket option SO_KEEPALIVE. Set arguments to TRUE to turn this option on or to FALSE to turn it off. |
SO-REUSEADDR | Sets the TCP socket option SO_REUSEADDR. Set arguments to TRUE to turn this option on or to FALSE to turn it off. |
SO-RCVBUF SO-SNDBUF |
Sets the TCP socket option SO_RCVBUF or SO_SNDBUF. Set arguments to the desired size of the buffer. Note: Depending on your platform, the value you supply might be increased to
the platform's minimum buffer size, decreased to the platform's maximum buffer
size, or rounded up to the next multiple of the platform's segment size. For more
information, see your platform's documentation.
|
SO-RCVTIMEO | Sets the timeout length—that is, the number of seconds the socket
waits to receive data before timing out. Set arguments to the desired timeout value in seconds. If a timeout occurs, READ( ) returns TRUE and the value of BYTES-READ is zero. This is true whether the READ( ) mode is READ-AVAILABLE or READ-EXACT-NUM. For more information on the interaction of READ( ), the READ( ) mode, and SO_RCVTIMEO, see OpenEdge Development: Programming Interfaces. |
The SET-SOCKET-OPTION( ) method returns TRUE if setting the option succeeded and returns FALSE otherwise. An error can occur if:
