get_clock_time


Description:

public int64 get_clock_time (Context context)

Returns the current time value from Cogl's internal clock.

This clock is used for measuring times such as the presentation time in a FrameInfo.

This method is meant for converting timestamps retrieved from Cogl to other time systems, and is not meant to be used as a standalone timing system. For that reason, if this function is called without having retrieved a valid (non-zero) timestamp from Cogl first, it may return 0 to indicate that Cogl has no active internal clock.

Parameters:

context

a Context pointer

Returns:

the time value for the Cogl clock, in nanoseconds from an arbitrary point in time, or 0 if Cogl doesn't have an active internal clock.
