SYNOPSIS
- int scsi_mode_sense(struct scsi_device * sdev, int dbd, int modepage, unsigned char * buffer, int len, int timeout, int retries, struct scsi_mode_data * data, struct scsi_sense_hdr * sshdr);
ARGUMENTS
sdev
-
- SCSI device to be queried
dbd
- set if mode sense will allow block descriptors to be returned
modepage
- mode page being requested
buffer
- request buffer (may not be smaller than eight bytes)
len
- length of request buffer.
timeout
- command timeout
retries
- number of retries before failing
data
- returns a structure abstracting the mode header data
sshdr
- place to put sense data (or NULL if no sense to be collected). must be SCSI_SENSE_BUFFERSIZE big.
