scsi_find_sense_descr(9F)Kernel Functions for Driversscsi_find_sense_descr(9F)NAMEscsi_find_sense_descr - find descriptor in SCSI sense data
SYNOPSIS
#include <sys/scsi/scsi.h>
uint8_t *scsi_find_sense_descr(uint8_t *sense_buffer, int sense_buf_len,
int req_descr_type);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
sense_buffer Pointer to a buffer containing SCSI descriptor sense
data. The data is expected in wire format starting at
the response code.
sense_buf_len Integer that contains the length of sense buffer in
bytes.
req_descr_type Integer that contains the descriptor type value for
the desired sense descriptor.
DESCRIPTION
The scsi_find_sense_descr() function is used to obtain a pointer to a
specific descriptor type, specified by req_descr_type, within a
descriptor sense buffer. Before returning the pointer,
scsi_find_sense_descr() verifies that the entire descriptor is present
based on the length provided in sense_buf_len.
Any value for req_descr_type can be requested. The following descriptor
types are already defined:
#define DESCR_INFORMATION 0x00
#define DESCR_COMMAND_SPECIFIC 0x01
#define DESCR_SENSE_KEY_SPECIFIC 0x02
#define DESCR_FRU 0x03
#define DESCR_STREAM_COMMANDS 0x04
#define DESCR_BLOCK_COMMANDS 0x05
#define DESCR_OSD_OID 0x06
#define DESCR_OSD_RESP_INTEGRITY 0x07
#define DESCR_OSD_ATTR_ID 0x08
Drivers should use scsi_validate_sense(9F) to ensure that the sense
buffer contains valid descriptor sense data.
RETURN VALUES
The scsi_find_sense_descr() function returns a pointer to a sense
descriptor of the requested type if a descriptor of that type exists.
If no such descriptor exists, scsi_find_sense_descr() returns NULL.
CONTEXT
The scsi_find_sense_descr() function can be called from user or inter‐
rupt context.
