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

NAME
makecom, makecom_g0, makecom_g0_s, makecom_g1, makecom_g5 - make a packet for SCSI commands SYNOPSIS
#include <sys/scsi/scsi.h> void makecom_g0(struct scsi_pkt *pkt, struct scsi_device *devp, int flag, int cmd, int addr, int cnt); void makecom_g0_s(struct scsi_pkt *pkt, struct scsi_device *devp, int flag, int cmd, int cnt, int fixbit); void makecom_g1(struct scsi_pkt *pkt, struct scsi_device *devp, int flag, int cmd, int addr, int cnt); void makecom_g5(struct scsi_pkt *pkt, struct scsi_device *devp, int flag, int cmd, int addr, int cnt); INTERFACE LEVEL
These interfaces are obsolete. scsi_setup_cdb(9F) should be used instead. PARAMETERS
pkt Pointer to an allocated scsi_pkt(9S) structure. devp Pointer to the target's scsi_device(9S) structure. flag Flags for the pkt_flags member. cmd First byte of a group 0 or 1 or 5 SCSI 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. fixbit Fixed bit in sequential access device commands. DESCRIPTION
makecom functions initialize a packet with the specified command descriptor block, devp and transport flags. The pkt_address, pkt_flags, and the command descriptor block pointed to by pkt_cdbp are initialized using the remaining arguments. Target drivers may use makecom_g0() for Group 0 commands (except for sequential access devices), or makecom_g0_s() for Group 0 commands for sequential access devices, or make- com_g1() for Group 1 commands, or makecom_g5() for Group 5 commands. fixbit is used by sequential access devices for accessing fixed block sizes and sets the the tag portion of the SCSI CDB. CONTEXT
These functions can be called from user or interrupt context. EXAMPLES
Example 1: Using makecom Functions if (blkno >= (1<<20)) { makecom_g1(pkt, SD_SCSI_DEVP, pflag, SCMD_WRITE_G1, (int) blkno, nblk); } else { makecom_g0(pkt, SD_SCSI_DEVP, pflag, SCMD_WRITE, (int) blkno, nblk); } ATTRIBUTES
See attributes(5) for a description of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Stability Level |Obsolete | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5), scsi_setup_cdb(9F), scsi_device(9S), scsi_pkt(9S) ANSI Small Computer System Interface-2 (SCSI-2) Writing Device Drivers NOTES
The makecom_g0(), makecom_g0_s(), makecom_g1(), and makecom_g5() functions are obsolete and will be discontinued in a future release. These functions have been replaced by the scsi_setup_cdb() function. See scsi_setup_cdb(9F). SunOS 5.10 27 Sep 2002 makecom(9F)
