vkGetDeviceQueueVkDevice

vkGetDeviceQueueVkDevice is a function within the Vulkan graphics API. Its purpose is to retrieve a handle to a queue that belongs to a specific logical device. A logical device represents an interface to a physical GPU, and queues are command-processing units within that device. These queues are used to submit command buffers, which contain graphics or compute operations.

The function takes several arguments. It requires a pointer to the VkDevice that the queue belongs to, and an unsigned integer specifying the queue index. This index identifies which queue from the device's available queues is being requested. Additionally, it takes a pointer to a VkQueue structure, which will be populated with the handle to the retrieved queue upon successful execution.

Vulkan applications typically use vkGetDeviceQueueVkDevice to obtain handles to queues that support specific queue families. Queue families group queues with similar capabilities, such as graphics, compute, or transfer operations. By requesting a queue from the appropriate family, developers can ensure they are using a queue optimized for the intended workload. The function returns a VkResult indicating whether the operation was successful or encountered an error.
