I would use kstats to be consistent with 'iostat -E'. E.g.:
#include <kstat.h>
#include <stdio.h>
#include <string.h>
#include <sys/sysinfo.h>
/* Usage: sn disk ...
e.g. sn sd0 sd1
*/
int
main(int argc, char **arg) {
kstat_ctl_t *kc;
kstat_t *ksp;
kstat_named_t *ksp_named;
char ks_name[KSTAT_STRLEN];
int i;
kid_t kcid;
kc = kstat_open();
argc--;
for (; argc > 0; argc--) {
printf("%s: ", arg[argc]);
snprintf(ks_name, sizeof(ks_name) - 2, "%s,err", arg[argc]);
if (ks_name[0] == 'c') {
strcat(ks_name, "or"); /* ide, otherwise assume sdN */
}
ksp = kstat_lookup(kc, NULL, -1, ks_name);
if (ksp != NULL && ksp->ks_type == KSTAT_TYPE_NAMED) {
kcid = kstat_read(kc, ksp, NULL);
if (kcid == -1) {
printf("error reading kstats \n");
continue;
}
ksp_named = ksp->ks_data;
for (i = 0; i < ksp->ks_ndata; i++, ksp_named++) {
if (ksp_named->data_type != KSTAT_DATA_CHAR) {
continue;
}
ksp_named->name[KSTAT_STRLEN - 1] = '\0';
if (strcmp(ksp_named->name, "Vendor") == 0) {
printf("Vendor=%s ", ksp_named->value.c);
} else if (strcmp(ksp_named->name, "Product") == 0) {
printf("Product=%s ", ksp_named->value.c);
} else if (strcmp(ksp_named->name, "Serial No") == 0) {
printf("S/N=%s ", ksp_named->value.c);
} else if (strcmp(ksp_named->name, "Model") == 0) {
printf("Model=%s ", ksp_named->value.c);
} else if (strcmp(ksp_named->name, "Revision") == 0) {
printf("Rev=%s ", ksp_named->value.c);
}
}
printf("\n");
}
}
(void) kstat_close(kc);
return (0);
}
But there are probably other alternatives ;-)
Have fun,
jel.
