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); 
}
