Kernel Functions for Drivers            scsifindsensedescr(9F)



NAME
     scsifindsensedescr - find descriptor in SCSI sense data

SYNOPSIS
     #include 



     uint8t *scsifindsensedescr(uint8t *sensebuffer, int sensebuflen,
          int reqdescrtype);


INTERFACE LEVEL
     Solaris DI specific (Solaris DI).

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


     sensebuflen     Integer that contains the length of  sense
                       buffer in bytes.


     reqdescrtype    Integer that contains the descriptor  type
                       value for the desired sense descriptor.


DESCRIPTION
     The scsifindsensedescr() function is  used  to  obtain  a
     pointer   to   a  specific  descriptor  type,  specified  by
     reqdescrtype, within a  descriptor  sense  buffer.  Before
     returning the pointer, scsifindsensedescr() verifies that
     the entire descriptor is present based on  the  length  pro-
     vided in sensebuflen.


     Any value for reqdescrtype can be requested. The following
     descriptor types are already defined:

       #define DESCRINFORMATION         0x00
       #define DESCRCOMANDSPECIFIC    0x01
       #define DESCRSENSEKEYSPECIFIC  0x02
       #define DESCRFRU                 0x03
       #define DESCRSTREAMCOMANDS     0x04
       #define DESCRBLOCKCOMANDS      0x05
       #define DESCROSDOID             0x06
       #define DESCROSDRESPINTEGRITY  0x07
       #define DESCROSDATRID         0x08

Kernel Functions for Drivers            scsifindsensedescr(9F)



     Drivers should use scsivalidatesense(9F)  to  ensure  that
     the sense buffer contains valid descriptor sense data.

RETURN VALUES
     The scsifindsensedescr() function returns a pointer to  a
     sense  descriptor  of  the requested type if a descriptor of
     that  type   exists.   If   no   such   descriptor   exists,
     scsifindsensedescr() returns NUL.

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