+ * Description:
+ *   Add a new route to the routing table.  This is just a convenience

+ * Parameters:
+ *   sockfd   - Any socket descriptor
+ *   target   - Target address (required)
+ *   netmask  - Network mask defining the sub-net (required)
+ *
+ * Returned Value:
+ *   OK on success; -1 on failure with the errno variable set appropriately.
