# scsi\_mode\_sense(9)

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

## 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.
