API Naming Conventions - cmbruns/pyopenxr Wiki

Many types, symbols, functions, and parameters are named differently in pyopenxr, compared to the C API.

For example, an intial "Xr" or "XR_" prefix is stripped off of the C API symbol, because in the python API, these symbols are in the "xr" module.

An exception is string values, which are the same in the python and C APIs. Both input string parameters and string result parameters are the same.

symbol Python example C example
function xr.create_instance(...) xrCreateInstance(...)
constant xr.MAX_SYSTEM_NAME_SIZE XR_MAX_SYSTEM_NAME_SIZE
struct name xr.ExtensionProperties XrExtensionProperties
type alias xr.Version XrVersion
enum type xr.FormFactor xrFormFactor
enum value xr.FormFactor.HEAD_MOUNTED_DISPLAY XR_FORM_FACTOR_HEAD_MOUNTED_DISPLAY
