So don't use these.
In theory, any use of #define TRUE / FALSE or enum bool or plain use of raw 0 and 1 is fine - but only as long as you make sure to use this consistently within the whole project.
If I am forced to use something like this, I prefer the enum as this can be decoded by a debugger. But in general, I try to avod it, and use plain C logic instead - because then I can just read and understand the code, in all other cases I have to look up definitions, especially when it comes to parameter passings.
In your specific case, you use TRUE and FALSE just in one single place, for one single variable. Dumpt that. Use 0 and 1, and everybody can read the code.
Thanks for explaining so well. I shall be sending V2 incorporating your suggestion.
