Question about 14.2 and the controlling variable

[triboix]

Hello,

14.2 states that the "controlling variable" must be of essentially boolean type.

Does that mean that the following code is non-compliant?

Code:

struct stuff
{
    uint32_t id;
};
struct stuff stuff_array[MAXSTUFF];

struct stuff* stuff_lookup(uint32_t id)
{
    uint8_t i;
    struct stuff* found = NULL;
    for (i = 0; (i < MAXSTUFF) && (found == NULL); i++) {
        if (stuff_array[i].id == id) {
            found = &(stuff_array[i]);
        }
    }
    return found;
}

Thanks a lot for any help!
