tran_getcap(9E) 						Driver Entry Points						   tran_getcap(9E)

NAME
tran_getcap, tran_setcap - get/set SCSI transport capability SYNOPSIS
#include <sys/scsi/scsi.h> int prefixtran_getcap(struct scsi_address *ap, char *cap, int whom); int prefixtran_setcap(struct scsi_address *ap, char *cap, int value, int whom); INTERFACE LEVEL
Solaris architecture specific (Solaris DDI). PARAMETERS
ap Pointer to the scsi_address(9S) structure. cap Pointer to the string capability identifier. value Defines the new state of the capability. whom Specifies whether all targets or only the specified target is affected. DESCRIPTION
The tran_getcap() and tran_setcap() vectors in the scsi_hba_tran(9S) structure must be initialized during the HBA driver's attach(9E) to point to HBA entry points to be called when a target driver calls scsi_ifgetcap(9F) and scsi_ifsetcap(9F). tran_getcap() is called to get the current value of a capability specific to features provided by the HBA hardware or driver. The name of the capability cap is the NULL terminated capability string. If whom is non-zero, the request is for the current value of the capability defined for the target specified by the scsi_address(9S) structure pointed to by ap; if whom is 0, all targets are affected; else, the target specified by the scsi_address structure pointed to by ap is affected. tran_setcap() is called to set the value of the capability cap to the value of value. If whom is non-zero, the capability should be set for the target specified by the scsi_address(9S) structure pointed to by ap; if whom is 0, all targets are affected; else, the target specified by the scsi_address structure pointed to by ap is affected. It is recommended that HBA drivers do not support setting capabilities for all targets, that is, whom is 0. A device may support only a subset of the defined capabilities. Refer to scsi_ifgetcap(9F) for the list of defined capabilities. HBA drivers should use scsi_hba_lookup_capstr(9F) to match cap against the canonical capability strings. RETURN VALUES
tran_setcap() must return 1 if the capability was successfully set to the new value, 0 if the HBA driver does not support changing the capability, and -1 if the capability was not defined. tran_getcap() must return the current value of a capability or -1 if the capability was not defined. SEE ALSO
