Platform type in Unix
Hi all,

How does one get the platform type in UNIX (for e.g. sparc/i386)? I need an function call and not the command like uname -p.

thanks!

See if you have the uname system call available on your machine. Check for man 2 uname

It is there but it doesn't give platform type/architecture Smilie

You are seeing a following example.

Code:
#include <sys/utsname.h>

main()
{
    struct utsname sys_inf;

    uname(&sys_inf);

    printf("System name - %s \n", sys_inf.sysname);
    printf("Nodename    - %s \n", sys_inf.nodename);
    printf("Release     - %s \n", sys_inf.release);
    printf("Version     - %s \n", sys_inf.version);
    printf("Machine     - %s \n", sys_inf.machine);
}

Best regards,
Iliyan Varshilov

Does this mean you are running compiled code? If so you should already know what architecture, or at least the compiler does.

For example, a C compiler may predefine one of the following as #defines:

__ppc__
__386__
__x86_64__
__mips__
__sparc__ or __sparc
__hppa
__alpha

Also, look at "config.guess"

    printf("Machine     - %s \n", sys_inf.machine);
}

But none of them gives processor architecture Smilie
