tran_tgt_free 9E "1 Nov 1993" "SunOS 5.11" "Driver Entry Points"
NAME
tran_tgt_free - request to free HBA resources allocated on behalf of a target
SYNOPSIS

#include <sys/scsi/scsi.h>



void prefixtran_tgt_free(dev_info_t *hba_dip, dev_info_t *tgt_dip,
 scsi_hba_tran_t *hba_tran, struct scsi_device *sd);
INTERFACE LEVEL

Solaris architecture specific (Solaris DDI).

PARAMETERS

hba_dip

Pointer to a dev_info_t structure, referring to the HBA device instance.

tgt_dip

Pointer to a dev_info_t structure, referring to the target device instance.

hba_tran

Pointer to a scsi_hba_tran(9S) structure, consisting of the HBA's transport vectors.

sd

Pointer to a scsi_device(9S) structure, describing the target.

DESCRIPTION

The tran_tgt_free() vector in the scsi_hba_tran(9S) structure may be initialized during the HBA driver's attach(9E) to point to an HBA driver function to be called by the system when an instance of a target device is being detached. The tran_tgt_free() vector, if not NULL, is called after the target device instance has returned successfully from its detach(9E) entry point, but before the dev_info node structure is removed from the system. The HBA driver should release any resources allocated during its tran_tgt_init() or tran_tgt_probe() initialization performed for this target device instance.
