public Class KHRConvertTimespecTime

The extension name.

The extension specification version.

Unsafe version of: ConvertTimespecTimeToTimeKHR

Convert timespec monotonic time to XrTime.

C Specification

To convert from timespec monotonic time to XrTime, call:

XrResult xrConvertTimespecTimeToTimeKHR(
    XrInstance                                  instance,
    const struct timespec*                      unixTime,
    XrTime*                                     time);

Description

The ConvertTimespecTimeToTimeKHR function converts a time obtained by the clock_gettime function to the equivalent XrTime.

If the output time cannot represent the input timespecTime, the runtime must return ERROR_TIME_INVALID.

Valid Usage (Implicit)

• The XR_KHR_convert_timespec_time extension must be enabled prior to calling ConvertTimespecTimeToTimeKHR
• instance must be a valid XrInstance handle
• unixTime must be a pointer to a valid timespec value
• time must be a pointer to an XrTime value

Return Codes

On success, this command returns

• SUCCESS

On failure, this command returns

• ERROR_FUNCTION_UNSUPPORTED
• ERROR_VALIDATION_FAILURE
• ERROR_RUNTIME_FAILURE
• ERROR_HANDLE_INVALID
• ERROR_INSTANCE_LOST
• ERROR_TIME_INVALID

Parameters

instance:XrInstance

an XrInstance handle previously created with CreateInstance.

time:LongBuffer

the resulting XrTime that is equivalent to the timespecTime.

Annotations

@NativeType:XrResult

Convert XrTime to timespec monotonic time.

C Specification

To convert from XrTime to timespec monotonic time, call:

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

Description

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

If the output timespecTime cannot represent the input time, the runtime must return ERROR_TIME_INVALID.

Valid Usage (Implicit)

• The XR_KHR_convert_timespec_time extension must be enabled prior to calling ConvertTimeToTimespecTimeKHR
• instance must be a valid XrInstance handle
• timespecTime must be a pointer to a timespec value

Return Codes

On success, this command returns

• SUCCESS

On failure, this command returns

• ERROR_FUNCTION_UNSUPPORTED
• ERROR_VALIDATION_FAILURE
• ERROR_RUNTIME_FAILURE
• ERROR_HANDLE_INVALID
• ERROR_INSTANCE_LOST
• ERROR_TIME_INVALID

Parameters

instance:XrInstance

an XrInstance handle previously created with CreateInstance.

time:long

an XrTime.

timespecTime:long

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