xrConvertTimeToTimespecTimeKHR(3)

C Specification

To convert from basetype::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 basetype::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 basetype::XrTime to time as if generated by clock_gettime.

Valid Usage (Implicit)

The [XR_KHR_convert_timespec_time] extension must be enabled prior to calling xrConvertTimeToTimespecTimeKHR
instance must be a valid XrInstance handle
timespecTime must be a pointer to a timespec value

Return Codes

On success, this command returns

XR_SUCCESS

On failure, this command returns

XR_ERROR_HANDLE_INVALID
