VkGetLatencyMarkerInfoNV

The VkGetLatencyMarkerInfoNV structure is defined as:

typedef struct VkGetLatencyMarkerInfoNV {
    VkStructureType sType;
    const void* pNext;
    uint32_t timingCount;
    VkLatencyTimingsFrameReportNV* pTimings;
} VkGetLatencyMarkerInfoNV;

• sType is a VkStructureType value identifying this structure.
• pNext is either NULL or a pointer to a structure extending this structure.
• timingCount is an integer related to the number of previous frames of latency data available or queried, as described below.
• pTimings is either NULL or a pointer to an array of VkLatencyTimingsFrameReportNV structures.

If pTimings is NULL then the maximum number of queryable frame data is returned in timingCount. Otherwise, timingCount must be set by the application to the number of elements in the pTimings array, and on return the variable is overwritten with the number of values actually written to pTimings. The elements of pTimings are arranged in the order they were requested in, with the oldest data in the first entry.
