An application using external memory may wish to synchronize access to that
|
||
|
|
memory using fences.
|
||
|
|
This extension enables an application to export fence payload to and import
|
||
|
|
fence payload from POSIX file descriptors.

=== Issues
|
||
|
|
|
||
|
|
This extension borrows concepts, semantics, and language from
|
||
|
|
<<VK_KHR_external_semaphore_fd,VK_KHR_external_semaphore_fd>>.
|
||
|
|
That extension's issues apply equally to this extension.
