NAME
     scsivalidatesense - find descriptor in SCSI sense data

SYNOPSIS
     #include 



     int scsivalidatesense(uint8t *sensebuffer, int sensebuflen,
          int *flags);


INTERFACE LEVEL
     Solaris DI specific (Solaris DI).

PARAMETERS
     sensebuffer     Pointer to a buffer containing  SCSI  sense
                      data.  The  sense  data is expected in wire
                      format starting at the response code.


     sensebuflen    Length of sense buffer in bytes.


     flags            Returns additional properties of the  sense
                      data.


DESCRIPTION
     The scsivalidatesense() function returns the format of the
     sense  data  contained  in the provided sense buffer. If the
     response code field in the sense data is not  recognized  or
     if there is not enough sense data to include sense key, asc,
     and ascq then scsivalidatesense() returns  SENSEUNUSABLE.
     If  the  buffer  contains usable sense data in fixed format,
     the function returns SENSEFIXEDFORMAT. If the buffer  con-
     tains  usable  sense data in descriptor format, the function
     returns SENSEDESCRFORMAT.


     The following flags may be set as appropriate  depending  on
     the sense data:

     SNSBUFOVERFLOW    The sense data buffer provided  for  the
                         request  is  too  small  to hold all the
                         sense data.


     SNSBUFDEFERED    The sense data contained in  the  buffer
                         relates  to  an  error that has occurred
                         during the processing of a  successfully
                         completed  command,  such  as  a  cached

                         write that could not be commited to  the
                         media.


RETURN VALUES
     SENSEUNUSABLE        The response code from the sense  data
                           is  unrecognized  or  not enough sense
                           data present to provide the sense key,
                           asc, and ascq.


     SENSEFIXEDFORMAT    The sense data in  the  buffer  is  in
                           "fixed format".


     SENSEDESCRFORMAT    The sense data in  the  buffer  is  in
                           "descriptor format".


CONTEXT
     The scsivalidatesense() function can be called  from  user
     or interrupt context.
