sdi_rmevent(D3sdi)

sdi_rmevent -- remove a driver event handler

Synopsis

   #include <sys/scsi.h>
   #include <sys/sdi.h>
   #include <sys/ddi.h>

   int sdi_rmevent(struct sdi_event *event);

Description

sdi_addevent(D3sdi) and sdi_rmevent, together with sdi_notifyevent(D3sdi), implement a driver-to-driver communication mechanism for SDI SCSI drivers based on event codes and SCSI device types. sdi_rmevent removes event from an internal list of driver events, effectively unregistering the driver event handler.

The call to sdi_rmevent must match a previous call to sdi_addevent.

Arguments

event: a structure defining the parameters of the driver event, including the event code, SCSI device address, SCSI inquiry string, event-handling routine, and SCSI device type to which driver event applies

Return values

On success, SDI_RET_OK. On failure SDI_RET_ERR.

Usage

sdi_rmevent is called in the driver's unload or halt routines, for each sdi_addevent that was previously called.

Context and synchronization

Blockable context.

Applicable hardware

x86/Pentium compatible architectures

Version applicability

sdi: 2, 3, 4 target drivers.
