Suggestion - arraycheck
 
Code:
/* Usage
 * array - Array to check
 * size - Size of array

 * Description
 * Checks if any element of array has a non-zero value

 * Return
 * 1 when any element is non-zero or
 * 0 when all elements are undefined/reseted/untouched/equal to 0*/
native arraycheck(array[], size)

That isn't really useful and takes only like 3 lines of code to write. This won't make it into AMXX.

That is fine.

Just curious, what was the reason?

I just wanted to make sure that all connected players have claimed their daily reward bonus. The array turns 1 for each id and if all were claimed, a minigame(menu) shows up. Also for my personal votemap system. To check if all players have voted, a simple way of getting it and to save TIME, those 4 seconds.
Generally a better way retrieving statistics for an array.

What problem to write a stock?
PHP Code:
/* Usage
 * array - Array to check
 * size - Size of array

 * Description
 * Checks if any element of array has a non-zero value

 * Return
 * 1 when any element is non-zero or
 * 0 when all elements are undefined/reseted/untouched/equal to 0*/
stock arraycheck(array[], size)
{
    for(new i; i < size; i++) {
        if(array[i]) {
            return 1;
        }
    }
    return 0;
}

By using bitfields instead of an array of booleans you can use !varBitField to see if it's empty. It will return positive if any value is true.
Worth it? Probably not.

That is an option. But why not for other posibilities.

You're actually making it slower with a native. Number of instructions that needs a native to interact on a module are a lot more than a simple loop which iterates over an array (and without needing module dependencies)

That's not overpowered.
Code:
static cell AMX_NATIVE_CALL arrayset(AMX *amx, cell *params)
{
    cell value = params[2];

    if (!value)
    {
        memset(get_amxaddr(amx, params[1]), 0, params[3] * sizeof(cell));
    } else {
        int size = params[3];
        cell *addr = get_amxaddr(amx, params[1]);
        for (int i=0; i<size; i++)
        {
            addr[i] = value;
        }
    }

    return 1;
}
