C Specification
POSIX file descriptor memory handles compatible with Vulkan may also be created by non-Vulkan APIs using methods beyond the scope of this specification. To determine the correct parameters to use when importing such handles, call:
VkResult vkGetMemoryFdPropertiesKHR(
VkDevice device,
VkExternalMemoryHandleTypeFlagBits handleType,
int fd,
VkMemoryFdPropertiesKHR* pMemoryFdProperties);
Parameters
-
device
is the logical device that will be importingfd
. -
handleType
is the type of the handlefd
. -
fd
is the handle which will be imported. -
pMemoryFdProperties
is a pointer to a VkMemoryFdPropertiesKHR structure in which the properties of the handlefd
are returned.
