scsi_setup_cdb

scsi_setup_cdb(9F)					   Kernel Functions for Drivers 					scsi_setup_cdb(9F)

NAME

       scsi_setup_cdb - setup SCSI command descriptor block (CDB)

SYNOPSIS

       int scsi_setup_cdb(union scsi_cdb *cdbp, uchar_t cmd, uint_t addr, uint_t cnt, uint_t othr_cdb_data);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       cdbp	       Pointer to command descriptor block.

       cmd	       The first byte of the SCSI group 0, 1, 2, 4, or 5 CDB.

       addr	       Pointer to the location of the data.

       cnt	       Data  transfer  length  in  units  defined by the SCSI device type. For sequential devices cnt is the number of bytes.  For
		       block devices, cnt is the number of blocks.

       othr_cdb_data   Additional CDB data.

DESCRIPTION

       scsi_setup_cdb() function initializes a group 0, 1, 2, 4, or 5 type of command descriptor block pointed to by  cdbp using  cmd, addr,  cnt,
       othr_cdb_data.

       addr  should  be  set to 0 for commands having no addressing information (for example, group 0 READ command for sequential access devices).
       othr_cdb_data should be additional CDB data for Group 4 commands; otherwise, it should be set to 0.

       scsi_setup_cdb() function does not set the LUN bits in CDB[1] as the  makecom(9F) functions do.	Also, the fixed bit for sequential  access
       device commands is not set.

RETURN VALUES

       scsi_setup_cdb() returns:

       1	Upon success.

       0	Upon failure.

CONTEXT

       These functions can be called from a user or interrupt context.
