API Naming Conventions - cmbruns/pyopenxr GitHub 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
