CMClockConvertHostTimeToSystemUnits(_:)

Converts a host time from a core media time structure to the host time’s native units.

Declaration

func CMClockConvertHostTimeToSystemUnits(_ hostTime: CMTime) -> UInt64

Parameters

  • hostTime:

    The host time to convert.

Discussion

This function performs a scale conversion, not a clock conversion. It can be more accurate than CMTimeConvertScale(_:timescale:method:) because the system units may have a non-integer timescale.

In macOS, this function converts to the units of mach_absolute_time.
