How to identity processor architecture

[Pravin Shedage]

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;
}
