del_netisr Kernel Service

Purpose

Deletes a network software interrupt service routine from the Network Interrupt table.

Syntax

#include <sys/types.h>
#include <sys/errno.h>
#include <net/netisr.h>

int del_netisr ( soft_intr_level) u_short soft_intr_level;

Parameter

Item	Description
soft_intr_level	Specifies the software interrupt level to delete. This parameter must be greater than or equal to 0 and less than NETISR_MAX. Refer to netisr.h for the range of values of soft_intr_level that are already in use. Also, other kernel extensions that are not AIX® and that use network ISRs currently running on the system can make use of additional values not mentioned in netisr.h.

Description

The del_netisr kernel service deletes the network software interrupt service routine specified by the soft_intr_level parameter from the Network Software Interrupt table.

Execution Environment

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

Return Values

Item	Description
0	Indicates that the software interrupt service was successfully deleted.
ENOENT	Indicates that the software interrupt service was not found in the Network Software Interrupt table.

Example

To delete a software interrupt service from the Network Software Interrupt table, invoke the kernel service as follows:

del_netisr(NETISR_IP);

In this example, the software interrupt routine to be deleted is NETISR_IP.
