C Specification
To query the current counter value of a semaphore created with a
VkSemaphoreType of VK_SEMAPHORE_TYPE_TIMELINE from the host,
call:
// Provided by VK_VERSION_1_2
VkResult vkGetSemaphoreCounterValue(
    VkDevice                                    device,
    VkSemaphore                                 semaphore,
    uint64_t*                                   pValue);or the equivalent command
// Provided by VK_KHR_timeline_semaphore
VkResult vkGetSemaphoreCounterValueKHR(
    VkDevice                                    device,
    VkSemaphore                                 semaphore,
    uint64_t*                                   pValue);Parameters
- 
deviceis the logical device that owns the semaphore.
- 
semaphoreis the handle of the semaphore to query.
- 
pValueis a pointer to a 64-bit integer value in which the current counter value of the semaphore is returned.
Description
| Note | If a queue submission command is pending execution, then the value returned by this command may immediately be out of date. |
