android - Equivalent of System.nanoTime() for NDK apps? -


my android ndk c++ application receives touch events , uses amotionevent_geteventtime() time of touch event. need compare time time values sample on own during app execution. function docs gives time "in java.lang.system.nanotime() time base", need have equivalent of call in c++ code.
best clue got clock_gettime(clock_monotonic) that?

found implementation of system.nanotime:
