// FUNCTION NAME: NvAPI_Initialize
//
//! This function initializes the NvAPI library (if not already initialized) but always increments the ref-counter. 
//! This must be called before calling other NvAPI_ functions.
//! Note: It is now mandatory to call NvAPI_Initialize before calling any other NvAPI.

// FUNCTION NAME: NvAPI_Unload
//
//!   DESCRIPTION: Decrements the ref-counter and when it reaches ZERO, unloads NVAPI library. 
//!                This must be called in pairs with NvAPI_Initialize. 
//!
//! SUPPORTED OS:  Windows 7 and higher
//!
//!
//!        If the client wants unload functionality, it is recommended to always call NvAPI_Initialize and NvAPI_Unload in pairs.
//!
//!  Unloading NvAPI library is not supported when the library is in a resource locked state.
//!  Some functions in the NvAPI library initiates an operation or allocates certain resources
//!  and there are corresponding functions available, to complete the operation or free the
//!  allocated resources. All such function pairs are designed to prevent unloading NvAPI library.
//!
//!  For example, if NvAPI_Unload is called after NvAPI_XXX which locks a resource, it fails with
//!  NVAPI_ERROR. Developers need to call the corresponding NvAPI_YYY to unlock the resources, 
//!  before calling NvAPI_Unload again.
//!
//! \return      This API can return any of the error codes enumerated in #NvAPI_Status. If there are return error codes with 
//!              specific meaning for this API, they are listed below.
//! \retval      NVAPI_API_IN_USE       Atleast an API is still being called hence cannot unload requested driver.

// FUNCTION NAME:   NvAPI_DISP_GetMonitorColorCapabilities
//
//! DESCRIPTION:    This API returns all the color formats and bit depth values supported by a given DP monitor.
//!
//! USAGE:         Sequence of calls which caller should make to get the information.
//!                1. First call NvAPI_DISP_GetMonitorColorCapabilities() with pMonitorColorCapabilities as NULL to get the count.
//!                2. Allocate memory for color caps(NV_MONITOR_COLOR_CAPS) array.
//!                3. Call NvAPI_DISP_GetMonitorColorCapabilities() again with the pointer to the memory allocated to get all the
//!                   color capabilities.
//!
//!                Note :
//!                1. pColorCapsCount should never be NULL, else the API will fail with NVAPI_INVALID_ARGUMENT.
//!                2. *pColorCapsCount returned from the API will always be the actual count in any/every call.
//!                3. Memory size to be allocated should be (*pColorCapsCount * sizeof(NV_MONITOR_COLOR_CAPS)).
//!                4. If the memory allocated is less than what is required to return all the timings, this API will return the
//!                   amount of information which can fit in user provided buffer and API will return NVAPI_INSUFFICIENT_BUFFER.
//!                5. If the caller specifies a greater value for *pColorCapsCount in second call to NvAPI_DISP_GetMonitorColorCapabilities()
//!                   than what was returned from first call, the API will return only the actual number of elements in the color
//!                   capabilities array and the extra buffer will remain unused.

// FUNCTION NAME:   NvAPI_Mosaic_GetSupportedTopoInfo
//
//! DESCRIPTION:     This API returns information on the topologies and display resolutions
//!                  supported by Mosaic mode.
//!
//!                  NOTE: Not all topologies returned can be set immediately.
//!                        See 'OUT' Notes below.
//!
//!                  Once you get the list of supported topologies, you can call
//!                  NvAPI_Mosaic_GetTopoGroup() with one of the Mosaic topologies if you need
//!                  more information about it.
//!
//!     <b>'IN' Notes:</b>  pSupportedTopoInfo->version must be set before calling this function.
//!                  If the specified version is not supported by this implementation,
//!                  an error will be returned (NVAPI_INCOMPATIBLE_STRUCT_VERSION).
//!
//!     <b>'OUT' Notes:</b> Some of the topologies returned might not be valid for one reason or
//!                  another.  It could be due to mismatched or missing displays.  It
//!                  could also be because the required number of GPUs is not found.
//!                  At a high level, you can see if the topology is valid and can be enabled
//!                  by looking at the pSupportedTopoInfo->topoBriefs[xxx].isPossible flag.
//!                  If this is true, the topology can be enabled. If it
//!                  is false, you can find out why it cannot be enabled by getting the
//!                  details of the topology via NvAPI_Mosaic_GetTopoGroup().  From there,
//!                  look at the validityMask of the individual topologies.  The bits can
//!                  be tested against the NV_MOSAIC_TOPO_VALIDITY_* bits.
//!
//!                  It is possible for this function to return NVAPI_OK with no topologies
//!                  listed in the return structure.  If this is the case, it means that
//!                  the current hardware DOES support Mosaic, but with the given configuration
//!                  no valid topologies were found.  This most likely means that SLI was not
//!                  enabled for the hardware. Once enabled, you should see valid topologies
//!                  returned from this function.
//!    
//! SUPPORTED OS:  Windows 7 and higher
//!
//!
//! \since Release: 185

//!                  current overlap values. If there is no match, then the
//!                  returned brief has an 'enable' status of FALSE (since it

//!                This set of API is an extension of D3D11 support for tiled resource to allow a tiled texture2D array with mip packing.
//!                If any of API from this set is used, using all of them is highly recommended.
//!                It includes NvAPI_D3D11_CreateTiledTexture2DArray, NvAPI_D3D11_TiledTexture2DArrayGetDesc,

//!                Reminder: all API in this set other than NvAPI_D3D11_CreateTiledTexture2DArray won't has D3D Debug Layer information.
//!
//!                NvAPI_D3D11_CreateTiledTexture2DArray is an extension of ID3D11Device::CreateTexutre2D.
//!                Use this function to create a tiled Texture2D array with mip packing.
//!                Runtime doesn't know the created resource is actually a tiled resource.
//!                Any other D3D11 API where runtime will check whether resource is tiled or not has a corresponding NVAPI version and they should be used.
//!                Different from DX12 implementation, this API should only be called when creating a tiled texture2D array with mip packing.
//!                Other normal tiled resource following D3D spec must use the standard ID3D11Device::CreateTexutre2D to create.

//!                Outputting a viewport mask allows a single primitive to land on many different viewports
//!                as specified by the bits set in the mask, rather than to rely on a single number that tells it
//!                which unique viewport it would be drawn on.
//!                This can be used for example in conjunction with the setting of coordinates swizzling (see XXX_NVAPI function)
//!                to generates multiple adjacent views of the same primitive in a more efficient fashion

//!                coding style, rather than converting a standard GS. For the explicit coding
//!                style, the GS must be written with maxvertexcount(1), and must pass-through
//!                input vertex 0 to the output without modification.
//!
//!                Additional per-primitive outputs may also be computed and written to the single
//!                output vertex. If these outputs are read by the pixel shader, they must be
//!                declared with the "nointerpolation" attribute in the PS input signature;
//!                otherwise, visual corruption may occur. Also, unlike D3D API, there is no guarantee 
//!                that pixel shader will get the default value of an attribute if that attribute is not written 
//!                by the earlier shader stage in the pipeline.
//!
//!                The first four parameters are identical to ID3D11Device::CreateGeometryShader(),

// FUNCTION NAME: NvAPI_D3D12_CreateReservedResource
//
//! \since Release: 375
//
//! \code
//!   DESCRIPTION: Tiled resource is supported for Texture2D Array, however, but only when mip packing is not triggered.
//!                So any mip level cannot be smaller than a single tile size(64KB).
//!                This set of API is an extension of D3D12 support for tiled resource to allow a tiled texture2D array with mip packing.
//!                If any of API from this set is used, using all of them is highly recommended.
//!                It includes NvAPI_D3D12_CreateReservedResource, NvAPI_D3D12_CreateHeap, NvAPI_D3D12_ReservedResourceGetDesc,
//!                NvAPI_D3D12_UpdateTileMappings, NvAPI_D3D12_CopyTileMappings, NvAPI_D3D12_ResourceAliasingBarrier.
//!                Reminder: all API in this set other than NvAPI_D3D12_CreateReservedResource won't has D3D Debug Layer information.
//!
//!                NvAPI_D3D12_CreateReservedResource is an extension of ID3D12Device::CreateReservedResource.
//!                Use this function to create a tiled Texture2D array with mip packing.
//!                Runtime doesn't know the created resource is actually a tiled resource.
//!                Any other D3D12 API where runtime will check whether resource is tiled or not, has a corresponding NVAPI version and they should be used.
//!                Different from DX11 implementation, we highly recommend replace all ID3D12Device::CreateReservedResource with NvAPI_D3D12_CreateReservedResource, 
//!                and use bTexture2DArrayMipPack to control which creation to use.
//!                Otherwise, NvAPI_D3D12_ResourceAliasingBarrier will fail if any resource is not created by NvAPI_D3D12_CreateReservedResource.
//!                DX11 implementation doesn't have this restriction and resource created by NVAPI and D3D API can be used together.
//!                pHeap is necessary when bTexture2DArrayMipPack is true. pHeap can be any heap and this API doens't change anything to it.
//!
//!         \param [in]        pDevice                A pointer to D3D12 device.
//!         \param [in]        pDesc                  A pointer to a D3D12_RESOURCE_DESC structure that describes the resource.
//!         \param [in]        InitialState           The initial state of the resource, as a bitwise-OR'd combination of D3D12_RESOURCE_STATES enumeration constants.

//!                The name of the key is automatically set to the name of the executable that calls this function.
//!                Because of this, the executable should have a distinct and unique name.
//!                If the application is using only one version of DirectX, then the default profile type will be appropriate.

//!                it should use the appropriate profile type for each configuration profile.
//!
//! HOW TO USE:    When there is a need for an application to have default stereo parameter values,

//!               If the the display is prohibited from showing stereo (e.g. secondary in a multi-mon setup), we will 
//!               return 0 for all stereo modes (full screen exclusive, automatic windowed, persistent windowed).
//!               Otherwise, we will check which stereo mode is supported. On 120Hz display, this will be what
//!               the user chooses in control panel. On HDMI 1.4 display, persistent windowed mode is always assumed to be
//!               supported. Note that this function does not check if the CURRENT RESOLUTION/REFRESH RATE can support
//!               stereo. For HDMI 1.4, it is the app's responsibility to change the resolution/refresh rate to one that is
//!               3D compatible. For 120Hz, the driver will ALWAYS force 120Hz anyway.
