What are the most common naming conventions in C?

Question

What are the naming conventions commonly use in C? I know there are at least two:

1. GNU / linux / K&R with lower_case_functions
2. ? name ? with UpperC

Answer 1

You should also think about the order of the words to make the auto name completion easier.

A good practice: library name + module name + action + subject

If a part is not relevant just skip it, but at least a module name and an action always should be presented.

Examples:

• function name: os_task_set_prio, list_get_size, avg_get
• define (here usually no action part): OS_TASK_PRIO_MAX
