CLAP_RENDER_REALTIME usage question

[J0ySF]

I am looking into the CLAP API since I need to develop a plugin which requires a constant processing rate to be used (no offline rendering allowed for example), and from my understanding the CLAP_EXT_RENDER extension seems to allow to implement what I am looking for.

Since I have found no examples online at the moment, I read the info in the https://github.com/free-audio/clap/blob/main/include/clap/ext/render.h header and implemented the extension like this:

bool render_has_hard_realtime_requirement(const clap_plugin_t *plugin) { return true; }
bool render_set(const clap_plugin_t *plugin, clap_plugin_render_mode mode) {
    return mode == CLAP_RENDER_REALTIME;
}
static const clap_plugin_render_t render = {
        .has_hard_realtime_requirement = render_has_hard_realtime_requirement,
        .set = render_set,
};

Does this configuration guarantee (on hosts what implement the extension) that each processing call will be issued at a constant rate (presumably at the ratio of $block size/sample rate$) or am I misunderstanding the extension's purpose?

This exactly what the extension is intended for.

Thanks a lot for the quick answer!
