[PD-dev] getting Pd logical time in C

[Miller Puckette]

Oh... I get it.  For that, the function is ugen_getsortno() -- returns
an integer which increases eachtime DSP is restarted.  You can add the
function call (to the ugen chain for instance) each time you see
ugen_getsortno() return an integer greater than the previous one you've
seen.

cheers
