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

NAME

       kstat_install - add a fully initialized kstat to the system

SYNOPSIS

       #include <sys/types.h>
       #include <sys/kstat.h>

       void kstat_install(kstat_t *ksp);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI)

PARAMETERS

       ksp	Pointer to a fully initialized kstat(9S) structure.

DESCRIPTION

       kstat_install() is used in conjunction with kstat_create(9F) to allocate and initialize a kstat(9S) structure.

       After  a  successful  call  to kstat_create() the driver must perform any necessary initialization of the data section (such as setting the
       name fields in a kstat of type  KSTAT_TYPE_NAMED). Virtual kstats must have the	ks_data field set at this time. The provider may also  set
       the  ks_update, ks_private, and ks_lock fields if necessary.

       Once the kstat is completely initialized, kstat_install is used to make the kstat accessible to the outside world.

RETURN VALUES

       None.

CONTEXT

       kstat_install() can be called from user or kernel context.

EXAMPLES

       Example 1: Allocating and Initializing a kstat Structure

	The method for allocating and initializing a kstat structure is generally as follows:

       kstat_t *ksp;
       ksp = kstat_create(module, instance, name, class, type, ndata, flags);
       if (ksp) {
		/* ... provider initialization, if necessary */
		 kstat_install(ksp);
       }
