* Name: net_delroute
|
|
*
|
|
* Description:
|
|
* Add a new route to the routing table. This is just a convenience
|
|
* wrapper for the SIOCADDRT ioctl call.
|
|
*
|
|
* Input Parameters:
|
|
* sockfd - Any socket descriptor
|
|
* target - Target address on the remote network (required)
|
|
* netmask - Network mask defining the external network (required)
|
|
*
|
|
* Returned Value:
|
|
* OK on success; -1 on failure with the errno variable set appropriately.
