oil_profile_stamp:
Creates a timestamp based on a CPU-specific high-frequency counter, if available.
Returns: a timestamp

SECTION:liboilprofile :OilProfile : Measuring the length of time needed to execute Liboil functions. oil_profile_init: : the OilProfile structure
Initializes a profiling structure.

oil_profile_get_ave_std: : the OilProfile structure : pointer to average : pointer to standard deviation
Calculates the average and standard deviation of a number of profiling runs, and places the results in the locations provided by and . Either and may be NULL, in which case the values will not be written.
oil_profile_start: : a pointer to an OilProfile structure
Starts a profiling run by obtaining a timestamp via oil_profile_stamp() and writing it into .
oil_profile_stop: : a pointer to an OilProfile structure
Stops a profiling run by obtaining a timestamp via oil_profile_stamp() and writing it into . It then calls oil_profile_stop_handle() to handle post-processing of the profiling run.
