Hello Everyone,
I want to get serial number of hardware with handling sysctl. I've got a
little code below:
#include <stdio.h>
#include <string.h>
#include <errno.h>
#include <sys/param.h>
#include <sys/sysctl.h>
int main(int argc, char **argv)
{
char cpubuf[1024];
size_t len;
int mib[5];
mib[0] = CTL_HW;
mib[1] = HW_SERIALNO;
len = sizeof(cpubuf);
if (sysctl(mib, 2, &cpubuf, &len, NULL, 0) == -1) {
printf("HW_SERIALNO %s\n", strerror(errno));
return(1);
}
printf("cpu: %s\n", cpubuf);
return 0;
}
But i realized that some of my machines cant get "sysctl hw.serialno" so
it's normal that C code fails with this error message : HW_SERIALNO
Operation not supported
So if we return to the source, why sysctl cant handle some of hardware
serial numbers?
Thank you.
P.S.
I want to provide a working sysctl.hw ouput here:
