C Specification

To convert from XrTime to timespec monotonic time, call:

XrResult xrConvertTimeToTimespecTimeKHR(
    XrInstance                                  instance,
    XrTime                                      time,
    struct timespec*                            timespecTime);

Parameters

Parameter Descriptions
  • instance is an XrInstance handle previously created with xrCreateInstance.

  • time is an XrTime.

  • unixTime is the resulting timespec time that is equivalent to a timespec obtained from clock_gettime with CLOCK_MONOTONIC.

Description

The xrConvertTimeToTimespecTimeKHR function converts an XrTime to time as if generated by clock_gettime.

If the output unixTime cannot represent the input time, the runtime must return XR_ERROR_TIME_INVALID.
