Function ovr_sys::ovr_GetTextureSwapChainLength [−] [src]

pub unsafe extern "C" fn ovr_GetTextureSwapChainLength(
    session: ovrSession, 
    chain: ovrTextureSwapChain, 
    out_Length: *mut c_int
) -> ovrResult

TextureSwapChain creation is rendering API-specific.

ovr_CreateTextureSwapChainDX, ovr_CreateTextureSwapChainGL and ovr_CreateTextureSwapChainVk can be found in the rendering API-specific headers, such as OVR_CAPI_D3D.h and OVR_CAPI_GL.h Gets the number of buffers in an ovrTextureSwapChain.

in session Specifies an ovrSession previously returned by ovr_Create.

in chain Specifies the ovrTextureSwapChain for which the length should be retrieved.

out out_Length Returns the number of buffers in the specified chain.

Returns an ovrResult for which OVR_SUCCESS(result) is false upon error.
