Hi,

This C program might help you.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <errno.h>
#include <sys/utsname.h>

int main()
{
    struct utsname *buf = NULL;



    buf = malloc(sizeof(struct utsname));
    if (buf == NULL) {
        fprintf(stderr,"Memory Allocation Error: %s \n", strerror(errno));
        exit(-1);
    }

    if (uname(buf) < 0) {
        fprintf(stderr,"UName Error: %s \n", strerror(errno));
        exit(-1);
    }

    printf ("Processor arch =:>) %s \n", buf->machine);

    return 0;
}

Any C programming technique apart from using this /proc/cpuinfo detail?

What about using the machine field of uname(2):

  $ man 2 uname

Quoting from that man page:

  [...] the operating system  presumably  knows  its name,  release
  and version.   It also knows what hardware it runs on.

Perhaps a downside, it returns the machine type as a string.  Does that
do what you want?

I also find "man linux32" rather interesting:

   setarch  -  change reported architecture in new program environment
   and set personality flags

Might be useful for testing.


Greetings,
Henry
