Purpose

Schedules or invokes a network software interrupt service routine.

Syntax 

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

int schednetisr ( anisr)
int anisr;

Parameter

Table 1. Parameter
Item Description
anisr Specifies the software interrupt number to issue. Refer to netisr.h for the range of values of anisr that are already in use. Also, other kernel extensions that are not AIX and that use network ISRs currently running on the system can use additional values that are not mentioned in netisr.h.

Description

The schednetisr kernel service schedules or calls a network interrupt service routine. The add_netisr kernel service establishes interrupt service routines. If the service was added with a service level of NET_OFF_LEVEL, the schednetisr kernel service directly calls the interrupt service routine. If the service level was NET_KPROC, a network kernel dispatcher is notified to call the interrupt service routine.

Execution Environment

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

Return Values

Table 2. Return Values
Item Description
EFAULT Indicates that a network interrupt service routine does not exist for the specified interrupt number.
EINVAL Indicates that the anisr parameter is out of range.
