// 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.
//!
//! SUPPORTED OS: Windows XP and higher, Mac OS X
//!
//!
//! \since Release: 80
//!
//! \retval NVAPI_ERROR An error occurred during the initialization process (generic error)

//
// 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 XP and higher, Mac OS X
//!
//!
//! Note: By design, it is not mandatory to call NvAPI_Initialize before calling any NvAPI.
//! When any NvAPI is called without first calling NvAPI_Initialize, the internal refcounter
//! will be implicitly incremented. In such cases, calling NvAPI_Initialize from a different thread will
//! result in incrementing the refcount again and the user has to call NvAPI_Unload twice to
//! unload the library. However, note that the implicit increment of the refcounter happens only once.
//! 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.
//!
//! \retval ::NVAPI_ERROR One or more resources are locked and hence cannot unload NVAPI library
//! \retval ::NVAPI_OK NVAPI library unloaded

// FUNCTION NAME: NvAPI_GPU_GetAllDisplayIds
//
//! DESCRIPTION: This API returns display IDs for all possible outputs on the GPU.
//! For DPMST connector, it will return display IDs for all the video sinks in the topology. \n
//! HOW TO USE: 1. The first call should be made to get the all display ID count. To get the display ID count, send in \n
//! a) hPhysicalGpu - a valid GPU handle(enumerated using NvAPI_EnumPhysicalGPUs()) as input, \n
//! b) pDisplayIds - NULL, as we just want to get the display ID count. \n
//! c) pDisplayIdCount - a valid pointer to NvU32, whose value is set to ZERO. \n
//! If all parameters are correct and this call is successful, this call will return the display ID's count. \n
//! 2. To get the display ID array, make the second call to NvAPI_GPU_GetAllDisplayIds() with \n
//! a) hPhysicalGpu - should be same value which was sent in first call, \n
//! b) pDisplayIds - pointer to the display ID array allocated by caller based on display ID count, \n
//! eg. malloc(sizeof(NV_GPU_DISPLAYIDS) * pDisplayIdCount). \n
//! c) pDisplayIdCount - a valid pointer to NvU32. This indicates for how many display IDs \n
//! the memory is allocated(pDisplayIds) by the caller. \n
//! If all parameters are correct and this call is successful, this call will return the display ID array and actual
//! display ID count (which was obtained in the first call to NvAPI_GPU_GetAllDisplayIds). If the input display ID count is
//! less than the actual display ID count, it will overwrite the input and give the pDisplayIdCount as actual count and the
//! API will return NVAPI_INSUFFICIENT_BUFFER.
//!
//! SUPPORTED OS: Windows XP and higher
//!
//!
//! \param [in] hPhysicalGpu GPU selection.
//! \param [in,out] DisplayIds Pointer to an array of NV_GPU_DISPLAYIDS structures, each entry represents one displayID
//! and its attributes.
//! \param [in,out] pDisplayIdCount As input, this parameter indicates the number of display's id's for which caller has

//! 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.

//! 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.

//! Once you get the list of supported topologies, you can call

//! 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

//! \fn NvAPI_D3D11_CreateFastGeometryShaderExplicit
//!
//! DESCRIPTION: This function will create a fast geometry shader written using an "explicit"
//! 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(),
//! so please refer to its documentation for their usage.
//!
//! \since Release:
//!
//! \param [in] pDevice The device pointer
//! \param [in] pShaderBytecode A pointer to the compiled shader.
//! \param [in] BytecodeLength Size of the compiled geometry shader.
//! \param [in] pClassLinkage A pointer to a class linkage interface. Can be NULL.
//! \param [in] pCreateFastGSArgs A pointer to a NvAPI_D3D11_CREATE_FASTGS_EXPLICIT struct.
//! \param [out] ppGeometryShader Address of a pointer to a ID3D11GeometryShader interface.

//! #NvAPI_Status. If there are return error codes with specific
//! meaning for this API, they are listed below.

//! If the application is using more than one version of DirectX from the same executable,

// FUNCTION NAME: NvAPI_Stereo_SetNotificationMessage
//
//! DESCRIPTION: This API is a Setup notification message that the stereo driver uses to notify the application
//! when the user changes the stereo driver state.
//!
//! When the user changes the stereo state (Activated or Deactivated, separation or conversion)
//! the stereo driver posts a defined message with the following parameters:
//!
//! lParam is the current conversion. (Actual conversion is *(float*)&lParam )
//!
//! wParam == MAKEWPARAM(l, h) where
//! - l == 0 if stereo is deactivated
//! - l == 1 if stereo is deactivated
//! - h is the current separation. (Actual separation is float(h*100.f/0xFFFF)
//!
//! Call this API with NULL hWnd to prohibit notification.
//!
//! WHEN TO USE: Use after the stereo handle for device interface is created via successful call to appropriate
//! NvAPI_Stereo_CreateHandleFrom() function.
//!
//!
//! SUPPORTED OS: Windows Vista and higher
//!
//!
//! \since Release: 180
