VkExternalFormatANDROID

VkExternalFormatANDROID is defined as:

typedef struct VkExternalFormatANDROID {
    VkStructureType sType;
    void* pNext;
    uint64_t externalFormat;
} VkExternalFormatANDROID;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• externalFormat is an implementation-defined identifier for the external format

When included in the pNext chain of another structure, it indicates additional format information beyond what is provided by VkFormat values for an Android hardware buffer. If externalFormat is zero, it indicates that no external format is used, and implementations should rely only on other format information. If this structure is not present, it is equivalent to setting externalFormat to zero.
