Example #1

File: hclib-runtime.c Project: habanero-rice/hclib

static inline void check_out_finish(finish_t *finish) {
    if (finish) {
        // hc_atomic_dec returns true when finish->counter goes to zero
        const int old = hc_atomic_dec(&(finish->counter));
        if (old == 1) {
            // If old was 1 and we decremented to 0
            hclib_promise_put(finish->finish_dep->owner, finish);
        }
    }
}

Example #2

File: fib.c Project: habanero-rice/hclib

    FibDDtArgs *args = raw_args;
    FibDDtArgs *lhs = promise_get(args->subres[0]);
    FibDDtArgs *rhs = promise_get(args->subres[1]);

    hclib_promise_put(args->res, args);
    // cleanup
    free_ddt_args(lhs);
