public class VkMemoryBarrier
extends Struct

Khronos Reference Page
Vulkan Specification

Specifies a global memory barrier. This type of barrier applies to memory accesses involving all memory objects that exist at the time of its execution.

Valid Usage

sType must be STRUCTURE_TYPE_MEMORY_BARRIER
pNext must be NULL
srcAccessMask must be a valid combination of VkAccessFlagBits values
dstAccessMask must be a valid combination of VkAccessFlagBits values

Member documentation

sType – the type of this structure. Must be: STRUCTURE_TYPE_MEMORY_BARRIER
pNext – reserved for use by extensions

srcAccessMask – a bitmask of the classes of memory accesses performed by the first set of commands that will participate in the dependency. One or more of:

`ACCESS_COLOR_ATTACHMENT_READ_BIT`	`ACCESS_COLOR_ATTACHMENT_WRITE_BIT`
`ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT`	`ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT`
`ACCESS_HOST_READ_BIT`	`ACCESS_HOST_WRITE_BIT`
`ACCESS_INDEX_READ_BIT`	`ACCESS_INDIRECT_COMMAND_READ_BIT`
`ACCESS_INPUT_ATTACHMENT_READ_BIT`	`ACCESS_MEMORY_READ_BIT`
`ACCESS_MEMORY_WRITE_BIT`	`ACCESS_SHADER_READ_BIT`
`ACCESS_SHADER_WRITE_BIT`	`ACCESS_TRANSFER_READ_BIT`
`ACCESS_TRANSFER_WRITE_BIT`	`ACCESS_UNIFORM_READ_BIT`
`ACCESS_VERTEX_ATTRIBUTE_READ_BIT`

dstAccessMask – a bitmask of the classes of memory accesses performed by the second set of commands that will participate in the dependency
