vkInvalidateMappedMemoryRanges - Invalidate ranges of mapped memory objects.
|
||
|
|
|
||
|
|
C Specification
|
||
|
|
---------------
|
||
|
|
|

Parameters
|
||
|
|
----------
|
||
|
|
|
||
|
|
pname:device::
|
||
|
|
A handle to the logical device which owns the specified memory ranges.
|
||
|
|
|
||
|
|
pname:memoryRangeCount::
|
||
|
|
Number of memory ranges described by pname:pMemoryRanges.
|
||
|
|
|
||
|
|
pname:pMemoryRanges::
|
||
|
|
Memory ranges to invalidate.
|
||
|
|
|
||
|
|
Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
fname:vkInvalidateMappedMemoryRanges invalidates a number of ranges of a number of mapped memory
|
||
|
|
objects. pname:device is the handle to the device that owns the memory objects referenced by
|
||
|
|
the call. pname:memoryRangeCount specifies the number of memory ranges to invalidate and pname:pMemoryRanges
|
||
|
|
is a pointer to an array of slink:VkMappedMemoryRange structures describing the memory ranges
|
||
|
|
to be invalidated. The definition of slink:VkMappedMemoryRange is:
|
||
|
|
|
||
|
|
include::../structs/VkMappedMemoryRange.txt[]
|
||
|
|
|
||
|
|
The pname:sType member of each element of pname:pMemoryRanges should be set to ename:VK_STRUCTURE_TYPE_MAPPED_MEMORY_RANGE.
|
||
|
|
The pname:memory member of the structure specifies the handle to the device memory object containing the
|
||
|
|
mapped region and pname:offset and pname:size specify the starting offset and size of the region, in bytes, respectively.
|
||
|
|
Areas of regions that extend outside the mapped portion of the parent memory object are ignored and
|
||
|
|
have no effect.
|
||
|
|
|
||
|
|
After invalidation, any data stored in the referenced region is discarded and should be considered
|
||
|
|
stale.
