KSTAT_INSTALL(9F) | Kernel Functions for Drivers | KSTAT_INSTALL(9F) |
#include <sys/types.h> #include <sys/kstat.h> void kstat_install(kstat_t *ksp);
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.
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); }
