Here is the caller graph for this function:

safeCall() [1/2]

template<typename T>

XrResult OpenXRHelpers::safeCall ( )

nodiscard

Safe call to OpenXR function.

Parameters

f	- OpenXR function pointer that returns a XrResult
args	- arguments for the function pointed to by f

Returns

a XrResult indicating the result of the function call.

Note

This function is used to "safely" call OpenXR functions without having to check if the function pointer is nullptr. If the function pointer is nullptr XR_ERROR_FUNCTION_UNSUPPORTED is returned.

If the function returns XR_ERROR_FUNCTION_UNSUPPORTED the caller should avoid calling the function again.

safeCall() [2/2]

template<typename... A>

XrResult OpenXRHelpers::safeCall ( XrResult(XRAPI_PTR *f)(A...) , A... args )
