del_input_type Kernel Service

AIX Version 4.3 Kernel and Subsystems Technical Reference, Volume 1

Deletes an input type from the Network Input table.

#include <net/if.h>

int del_input_type 
(type)
u_short type;

type

Specifies which type of protocol the packet contains. This parameter is a field in a packet.

The del_input_type kernel service deletes an input type from the Network Input table to disable the reception of the specified packet type.

The del_input_type kernel service can be called from either the process or interrupt environment.

0	Indicates that the type was successfully deleted.
ENOENT	Indicates that the del_input_type service could not find the type in the Network Input table.

To delete an input type from the Network Input table, invoke the del_input_type kernel service as follows:
```
del_input_type(ETHERTYPE_IP);
```
In this example, ETHERTYPE_IP specifies that Ethernet IP packets should no longer be processed.
To delete an input type from the Network Input table, invoke the del_input_type kernel service as follows:
```
del_input_type(ETHERTYPE_ARP);
```
In this example, ETHERTYPE_ARP specifies that Ethernet ARP packets should no longer be processed.

The del_input_type kernel service is part of Base Operating System (BOS) Runtime.
