C Specification

To define a set of external memory handle types that may be used as backing store for a buffer, add a VkExternalMemoryBufferCreateInfo structure to the pNext chain of the VkBufferCreateInfo structure. The VkExternalMemoryBufferCreateInfo structure is defined as:

typedef struct VkExternalMemoryBufferCreateInfo {
    VkStructureType                    sType;
    const void*                        pNext;
    VkExternalMemoryHandleTypeFlags    handleTypes;
} VkExternalMemoryBufferCreateInfo;

or the equivalent

typedef VkExternalMemoryBufferCreateInfo VkExternalMemoryBufferCreateInfoKHR;

Members

Note

A VkExternalMemoryBufferCreateInfo structure must be included in the creation parameters for a buffer that will be bound to memory that is either exported or imported.

Description

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • handleTypes is a bitmask of VkExternalMemoryHandleTypeFlagBits specifying one or more external memory handle types.
