NAME
scsi_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 interrupt context. SEE ALSO
