kstat_named(9S) Data Structures for Drivers kstat_named(9S)NAME
kstat_named - structure for named kstats
SYNOPSIS
#include <sys/types.h>
#include <sys/kstat.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
DESCRIPTION
Named kstats are an array of name-value pairs. These pairs are kept in the kstat_named structure. When a kstat is created by kstat_cre-
ate(9F), the driver specifies how many of these structures will be allocated. The structures are returned as an array pointed to by the
ks_data field.
STRUCTURE MEMBERS
union {
char c[16];
long l;
ulong_t ul;
longlong_t ll;
u_longlong_t ull;
} value; /* value of counter */
The only member exposed to drivers is the value member. This field is a union of several data types. The driver must specify which type it
will use in the call to kstat_named_init().

kstat_io - structure for I/O kstats
SYNOPSIS
#include <sys/types.h>
#include <sys/kstat.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
DESCRIPTION
I/O kstat statistics are kept in a kstat_io structure. When kstat_create(9F) creates an I/O kstat, the ks_data field is a pointer to one of
these structures. The macro KSTAT_IO_PTR() is provided to retrieve this field. It looks like this:
#define KSTAT_IO_PTR(kptr) ((kstat_io_t *)(kptr)->ks_data)
STRUCTURE MEMBERS
u_longlong_t nread; /* number of bytes read */
u_longlong_t nwritten; /* number of bytes written *]/
ulong_t reads; /* number of read operations */
ulong_t writes; /* number of write operations */
The nread field should be updated by the driver with the number of bytes successfully read upon completion.
The nwritten field should be updated by the driver with the number of bytes successfully written upon completion.
The reads field should be updated by the driver after each successful read operation.
The writes field should be updated by the driver after each successful write operation.
Other I/O statistics are updated through the use of the kstat_queue(9F) functions.

kstat_waitq_enter(9F), kstat_waitq_exit(9F), kstat_waitq_to_runq(9F)

Hi,
Humorous UNIX Commands shows a fun way of using echo and dc to sort of obfuscate a string.

Hi All,
Having recently started a new job, a Data Center Migration in fact I have been tasked with looking at some of the older Solaris boxes when I came across this little gem.

For any SunOS 5.XX release, it appears prior to the "login:" prompt (as if a "uname" command is run).
Would anyone know where that initial display of SunOS release comes from upon a remote login and how I can stop if from displaying?
Thank you (4 Replies)
