SCSI_MODE_SENSE(9)                        SCSI mid layer                       SCSI_MODE_SENSE(9)



NAME
       scsi_mode_sense - issue a mode sense, falling back from 10 to six bytes if necessary.

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.

DESCRIPTION
       Returns zero if unsuccessful, or the header offset (either 4 or 8 depending on whether a
       six or ten byte command was issued) if successful.
