kstat_install(9F)              Kernel Functions              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
       The kstat_install() function is used in conjunction with the kstat_cre‐
       ate() function to allocate and initialize a  kstat(9S)  structure.  For
       more information, see the kstat_create(9F) man page.


       After a successful call to the kstat_create() function, the driver must
       perform any necessary initialization of the data section (such as  set‐
       ting  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
       The kstat_install() function 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  gener‐
       ally as follows:




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

NOTES
       The use of the kstat_install() function is deprecated. The function may
       be  removed  in a future release of Oracle Solaris. Use the kstat2_cre‐
       ate() and kstat2_install() functions instead. For more information, see
       the kstat2_create(9F) and kstat2_install(9F) man pages.
