C Specification
To query the set of mixed sample combinations of coverage reduction mode, rasterization samples and color, depth, stencil attachment sample counts that are supported by a physical device, call:
// Provided by VK_NV_coverage_reduction_mode
VkResult vkGetPhysicalDeviceSupportedFramebufferMixedSamplesCombinationsNV(
VkPhysicalDevice physicalDevice,
uint32_t* pCombinationCount,
VkFramebufferMixedSamplesCombinationNV* pCombinations);
Parameters
-
physicalDeviceis the physical device from which to query the set of combinations. -
pCombinationCountis a pointer to an integer related to the number of combinations available or queried, as described below. -
pCombinationsis eitherNULLor a pointer to an array of VkFramebufferMixedSamplesCombinationNV values, indicating the supported combinations of coverage reduction mode, rasterization samples, and color, depth, stencil attachment sample counts.
Description
If pCombinations is NULL, then the number of supported combinations
for the given physicalDevice is returned in pCombinationCount.
Otherwise, pCombinationCount must point to a variable set by the user
to the number of elements in the pCombinations array, and on return
the variable is overwritten with the number of values actually written to
pCombinations.
If the value of pCombinationCount is less than the number of
combinations supported for the given physicalDevice, at most
pCombinationCount values will be written to pCombinations, and
VK_INCOMPLETE will be returned instead of VK_SUCCESS, to
indicate that not all the supported values were returned.
