C naming convention, module trigrams?
For my company, I'm writing naming conventions for embedded code in C language.

 - Function names must be named in lowerCamelCase() and start with a
   verb.
 - Global variables are in Maj_started_lower_case and are noun
   groups.

Exemple:

    void initCanDriver();
    uint8_t *Can_driver_buffer;

I have propositions to start our names with a module trigram?
Exemple:

    void CDR_init();
    uint8_t *CDR_buffer;

Pros of trigram methode:

 - clearly identify modules (and force to have modules)
 - avoid duplicate names

Cons of trigram methode:

 - actually, the majority of our codes don't really have modules, how to name a new function inside? We would have to define all modules.
 - often less readable [you have to know CDR is CAN Driver]

Do you think it is a good idea?
