Yes. I noticed several of them.
Warning goes away after replacing "/**" with "/*".

Now I am not sure if we fix it with replacing with "/*" or adding
definitions for each of these parameters. There will be too many
repetitions. All these functions take r, d, eventid, and rmid as
parameters. Also these are static functions.
