VkMemoryBarrier(3)

C Specification

The VkMemoryBarrier structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkMemoryBarrier {
    VkStructureType    sType;
    const void*        pNext;
    VkAccessFlags      srcAccessMask;
    VkAccessFlags      dstAccessMask;
} VkMemoryBarrier;

Members

sType is the type of this structure.
pNext is NULL or a pointer to a structure extending this structure.
srcAccessMask is a bitmask of VkAccessFlagBits specifying a source access mask.
dstAccessMask is a bitmask of VkAccessFlagBits specifying a destination access mask.

Description

The first access scope is limited to access types in the source access mask specified by srcAccessMask.

The second access scope is limited to access types in the destination access mask specified by dstAccessMask.

Valid Usage (Implicit)

VUID-VkMemoryBarrier-sType-sType
sType must be VK_STRUCTURE_TYPE_MEMORY_BARRIER
VUID-VkMemoryBarrier-pNext-pNext
pNext must be NULL
VUID-VkMemoryBarrier-srcAccessMask-parameter
srcAccessMask must be a valid combination of VkAccessFlagBits values
VUID-VkMemoryBarrier-dstAccessMask-parameter
dstAccessMask must be a valid combination of VkAccessFlagBits values
