# Naming

## Functions

Functions (and methods) use `PascalCase`.
Functions (but not methods) exposed in headers additionally use the prefix  `rt`: `rtLoadResource`.

## Types

Types (including C++ clases) use `snake_case`.
Types exposed in header files use the prefix `rt_`: `rt_aio_handle`.
This is often also done for "private" types in C/C++ files, but there it is not mandatory.

## Variables

Variables use `snake_case`.
Global variables use the prefix `g_`, while file-scope global variables use a single underscore as their prefix `_`.
Member variables of C++ classes (but not plain-old data C structs) use the prefix `m_`.

## Macros

Macros use `ALL_UPPER_CASE` with the `RT_` prefix.
This is also used for enum options.

## API and Interface Structs

API structs (like `rt_render_backend_api`) are collections of function pointers,
without any "object pointer" containing wrapped state.
They use the suffix `_api`.

Interface structs (like `rt_render_device_i`) also contain function pointers,
and additionally an "object pointer", usually called `o`, that points to some
stateful object. The function pointers in the interface usually take this object as their first parameter.
