SYNOPSIS
#include <sys/scsi/scsi.h>
int scsi_hba_lookup_capstr(char *capstr);
INTERFACE LEVEL
Solaris architecture specific (Solaris DDI).
PARAMETERS
capstr Pointer to a string
DESCRIPTION
The scsi_hba_lookup_capstr() function attempts to match capstr against
a known set of capability strings. If found, the defined index for the
matched capability is returned.
The following indices are defined for the capability strings listed
below.
SCSI_CAP_DMA_MAX
"dma-max" or "dma_max"
SCSI_CAP_MSG_OUT
"msg-out" or "msg_out"
SCSI_CAP_DISCONNECT
"disconnect"
SCSI_CAP_SYNCHRONOUS
"synchronous"
SCSI_CAP_WIDE_XFER
"wide-xfer" or "wide_xfer"
SCSI_CAP_PARITY
"parity"
SCSI_CAP_INITIATOR_ID
"initiator-id"
SCSI_CAP_UNTAGGED_QING
"untagged-qing"
SCSI_CAP_TAGGED_QING
"tagged-qing"
SCSI_CAP_ARQ
"auto-rqsense"
SCSI_CAP_LINKED_CMDS
"linked-cmds"
SCSI_CAP_SECTOR_SIZE
"sector-size"
SCSI_CAP_TOTAL_SECTORS
"total-sectors"
SCSI_CAP_GEOMETRY
"geometry"
SCSI_CAP_RESET_NOTIFICATION
"reset-notification"
SCSI_CAP_QFULL_RETRIES
"qfull-retries"
SCSI_CAP_QFULL_RETRY_INTERVAL
"qfull-retry-interval"
SCSI_CAP_LUN_RESET
"lun-reset"
SCSI_CAP_CDB_LEN
"max-cdb-length"
SCSI_CAP_TRAN_LAYER_RETRIES
"tran-layer-retries"
RETURN VALUES
The scsi_hba_lookup_capstr() function returns a non-negative index
value that corresponds to the capability string. If the string does not
match a known capability, -1 is returned.
CONTEXT
The scsi_hba_lookup_capstr() function can be called from user, inter‐
rupt, or kernel context.
