Ok, this seems pretty silly to me, because, it just
breaks down to bad coding style.

#include <u.h>
#include <libc.h>

enum {
    true,
    false,
};

// returns true if value IS found in every slot
// returns false if value is NOT found in every slot
int
gotvalue/*?*/(int * a, uint len, int val)
{
    uint xa;

    for(ua = 0; ua < len; ua++) {
        if(a[ua] != val)
            return false;
    }
    return true;
}

void
main(int argc, char * argv[])
{
    int a[100];

    // somehow "a" gets filled with values

    if(gotvalue(&a[0], sizeof(a), 0xdeadca75) == true)
        print("yay, we're true! \n");
    else
        print("ick. \n");

    exits(0);
}
