Detailed Description

Macro Definition Documentation

◆ VMA_STATS_STRING_ENABLED

#define VMA_STATS_STRING_ENABLED   1

Typedef Documentation

◆ PFN_vmaAllocateDeviceMemoryFunction

typedef void(VKAPI_PTR * PFN_vmaAllocateDeviceMemoryFunction) (VmaAllocator allocator, uint32_t memoryType, VkDeviceMemory memory, VkDeviceSize size)

Callback function called after successful vkAllocateMemory.

◆ PFN_vmaFreeDeviceMemoryFunction

typedef void(VKAPI_PTR * PFN_vmaFreeDeviceMemoryFunction) (VmaAllocator allocator, uint32_t memoryType, VkDeviceMemory memory, VkDeviceSize size)

Callback function called before vkFreeMemory.

◆ VmaAllocatorCreateInfo

Description of a Allocator to be created.

◆ VmaAllocatorFlagBits

Flags for created VmaAllocator.

◆ VmaAllocatorFlags

typedef VkFlags VmaAllocatorFlags

◆ VmaDeviceMemoryCallbacks

Set of callbacks that the library will call for vkAllocateMemory and vkFreeMemory.

Provided for informative purpose, e.g. to gather statistics about number of allocations or total amount of memory allocated in Vulkan.

◆ VmaStatInfo

typedef struct VmaStatInfo VmaStatInfo

Enumeration Type Documentation

◆ VmaAllocatorFlagBits

Flags for created VmaAllocator.

Enumerator
VMA_ALLOCATOR_EXTERNALLY_SYNCHRONIZED_BIT 

Allocator and all objects created from it will not be synchronized internally, so you must guarantee they are used from only one thread at a time or synchronized externally by you.

Using this flag may increase performance because internal mutexes are not used.

VMA_ALLOCATOR_FLAG_BITS_MAX_ENUM 

Function Documentation

◆ vmaBuildStatsString()

void vmaBuildStatsString ( VmaAllocator  allocator,
char **  ppStatsString,
VkBool32  detailedMap 
)

Builds and returns statistics as string in JSON format.

Parameters
[out]ppStatsStringMust be freed using vmaFreeStatsString() function.

◆ vmaCalculateStats()

void vmaCalculateStats ( VmaAllocator  allocator,
VmaStats pStats 
)

Retrieves statistics from current state of the Allocator.

◆ vmaCreateAllocator()

VkResult vmaCreateAllocator ( const VmaAllocatorCreateInfo pCreateInfo,
VmaAllocator *  pAllocator 
)

Creates Allocator object.

◆ vmaDestroyAllocator()

void vmaDestroyAllocator ( VmaAllocator  allocator)

Destroys allocator object.

◆ vmaFreeStatsString()

void vmaFreeStatsString ( VmaAllocator  allocator,
char *  pStatsString 
)

◆ vmaGetMemoryProperties()

void vmaGetMemoryProperties ( VmaAllocator  allocator,
const VkPhysicalDeviceMemoryProperties **  ppPhysicalDeviceMemoryProperties 
)

PhysicalDeviceMemoryProperties are fetched from physicalDevice by the allocator. You can access it here, without fetching it again on your own.

◆ vmaGetMemoryTypeProperties()

void vmaGetMemoryTypeProperties ( VmaAllocator  allocator,
uint32_t  memoryTypeIndex,
VkMemoryPropertyFlags *  pFlags 
)

Given Memory Type Index, returns Property Flags of this memory type.

This is just a convenience function. Same information can be obtained using vmaGetMemoryProperties().

◆ vmaGetPhysicalDeviceProperties()

void vmaGetPhysicalDeviceProperties ( VmaAllocator  allocator,
const VkPhysicalDeviceProperties **  ppPhysicalDeviceProperties 
)

PhysicalDeviceProperties are fetched from physicalDevice by the allocator. You can access it here, without fetching it again on your own.
