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::../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.
