VkBufferMemoryBarrier(3)
========================
Name
----
VkBufferMemoryBarrier - Structure specifying the parameters of a buffer memory barrier.
C Specification
---------------
// refBegin VkBufferMemoryBarrier Structure specifying the parameters of a buffer memory barrier.
The sname:VkBufferMemoryBarrier structure is defined as:
include::../api/structs/VkBufferMemoryBarrier.txt[]
Members
-------
* pname:sType is the type of this structure.
* pname:pNext is `NULL` or a pointer to an extension-specific structure.
* pname:srcAccessMask is a bitmask of the classes of memory accesses
performed by the first set of commands that will participate in
the dependency.
* pname:dstAccessMask is a bitmask of the classes of memory accesses
performed by the second set of commands that will participate in
the dependency.
* pname:srcQueueFamilyIndex is the queue family that is relinquishing
ownership of the range of pname:buffer to another queue, or
ename:VK_QUEUE_FAMILY_IGNORED if there is no transfer of ownership.
* pname:dstQueueFamilyIndex is the queue family that is acquiring
ownership of the range of pname:buffer from another queue, or
ename:VK_QUEUE_FAMILY_IGNORED if there is no transfer of ownership.
* pname:buffer is a handle to the buffer whose backing memory is affected
by the barrier.
* pname:offset is an offset in bytes into the backing memory for
pname:buffer; this is relative to the base offset as bound to the buffer
(see flink:vkBindBufferMemory).
* pname:size is a size in bytes of the affected area of backing memory for
pname:buffer, or ename:VK_WHOLE_SIZE to use the range from pname:offset
to the end of the buffer.
