Thanks to the quick reply from someone who didn't want to be named.
I was simply looking for the wrong thing. I wanted the GSI_PROC_TYPE
option to getsysinfo. The final code is:
#include <stdio.h>
#include <unistd.h>
#include <sys/sysinfo.h>
#include <machine/hal_sysinfo.h>
#include <machine/cpuconf.h>
int main(int argc,char *argv[])
{
int status=0;
long buf;
int st=0;
char *str;
status = getsysinfo(GSI_PROC_TYPE, &buf, sizeof(buf), st, NULL,NULL);
buf = buf & 0xffff;
CPU_TYPE_TO_TEXT(buf,str);
printf("status = 0, start = %d\n",st);
printf("\tcpu type = %d (%s)\n",buf,str);
}
The original mail follows.
