C Specification
To signal a semaphore created with a VkSemaphoreTypeKHR of
VK_SEMAPHORE_TYPE_TIMELINE_KHR
with a particular counter value, on the
host, call:
VkResult vkSignalSemaphoreKHR(
VkDevice device,
const VkSemaphoreSignalInfoKHR* pSignalInfo);
Parameters
-
device
is the logical device that owns the semaphore. -
pSignalInfo
is a pointer to an instance of the VkSemaphoreSignalInfoKHR structure containing information about the signal operation.
Description
When vkSignalSemaphoreKHR
is executed on the host, it defines and
immediately executes a semaphore
signal operation which sets the timeline semaphore to the given value.
The first synchronization scope is defined by the host execution model, but
includes execution of vkSignalSemaphoreKHR
on the host and anything
that happened-before it.
The second synchronization scope is empty.
