C Specification

The VkGetLatencyMarkerInfoNV structure is defined as:

// Provided by VK_NV_low_latency2
typedef struct VkGetLatencyMarkerInfoNV {
    VkStructureType                   sType;
    const void*                       pNext;
    uint32_t                          timingCount;
    VkLatencyTimingsFrameReportNV*    pTimings;
} VkGetLatencyMarkerInfoNV;

Members

  • 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.

Description

If pTimings is NULL then the maximum number of queryable frame data is returned in timingCount. Otherwise, timingCount must be set by the user 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.

Valid Usage (Implicit)

  • VUID-VkGetLatencyMarkerInfoNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_GET_LATENCY_MARKER_INFO_NV

  • VUID-VkGetLatencyMarkerInfoNV-pTimings-parameter
    If timingCount is not 0, and pTimings is not NULL, pTimings must be a valid pointer to an array of timingCount VkLatencyTimingsFrameReportNV structures
