tiny.mprompt.resumeMulti

1/// Returns a multi-shot handle for the same suspend, so a yield function converts its handle before2/// resuming the same suspend more than once. The caller uses the returned handle in place of3/// `resume_ptr`. Converting a one-shot handle allocates a record from the process allocator, and4/// the record starts with one reference. The program stops with a panic if that allocation fails. A5/// handle that is already multi-shot comes back unchanged.6pub fn resumeMulti(resume_ptr: *Resume) *Resume {7    if (resumeIsMulti(resume_ptr)) |_| {8        @branchHint(.unlikely);9        return resume_ptr;10    }1112    const p = resumeIsOnce(resume_ptr).?;13    const mr = processAllocator().create(MResume) catch fatal("unable to allocate multi-shot resume", .{});14    mr.* = .{15        .refcount = 1,16        .resume_count = 0,17        .prompt = p,18        .save = null,19        .tail_return_point = p.return_point,20    };21    return resumeAsMulti(mr);22}
