Function libpd_sys::libpd_process_double

pub unsafe extern "C" fn libpd_process_double(
    ticks: c_int, 
    inBuffer: *const f64, 
    outBuffer: *mut f64
) -> c_int

process interleaved double samples from inBuffer -> libpd -> outBuffer buffer sizes are based on # of ticks and channels where: size = ticks * libpd_blocksize() * (in/out)channels note: only full-precision when compiled with PD_FLOATSIZE=64 returns 0 on success
