Is clock() actually implemented ?

[GlennFR]

Hi, I'm working on many different // projects on the RP6502, one of which is a port of the PLASMA language.
I wanted to get the clock ticks value (in assembler) but the subroutine doesn't seem to be implemented in any of the std. libraries.
Although cc65/ca65 will correctly compile the call to clock() [or _clock], the linker can't find the actual subroutine to link to.
From the cc65 function reference, this should be a machine specific routine, so aught to be in rp6502.lib...
Any ideas, please?

I've investigated a bit further. In the RIA firmware main.c I see this

bool main_api(uint8_t operation)
{
    switch (operation)
    {
    case 0x01:
        pix_api_xreg();
        break;
    case 0x02:
        cpu_api_phi2();
        break;
    case 0x03:
        oem_api_codepage();
        break;
    case 0x04:
        rng_api_lrand();
        break;
    case 0x05:
        cpu_api_stdin_opt();
        break;
    case 0x0F:
        clk_api_clock();
        break;
    case 0x10:
        clk_api_get_res();
 ... and so on

Note the trap for 0x0F. But if I try

long get_ticks()
{
    return ria_call_long(0x0F);
}

I always get zero.

OK, this is my new code, still returns 0.
`static long Ticks;
int count, temp;

long get_ticks()
{
return ria_call_long(0x0F);
}

int main(void)
{
fprintf(stderr, "Please wait...\n");
fflush(stderr);
for (count=0; count < 32767; count++)
{
temp = temp - count;
}
Ticks = get_ticks();
fprintf(stderr, "Ticks = %u\n", Ticks);
fprintf(stderr, "Hello.\n");
return 0;
}`
But my other concern is that clock() doesn't appear in the library rp6502.lib...

%u isn't long. %lu is.

[GlennFR]

OK, my error for the format string, thanks.
BUT : rp6502.inc is missing the "0F" code; rp6502.lib is missing the clock() function.

It's not upstream yet but has been in the repo since January:
