OilProfile

typedef struct {
} OilProfile;

An opaque structure representing profiling information.

OIL_PROFILE_HIST_LENGTH

#define OIL_PROFILE_HIST_LENGTH 10

Internal definition of the number of histogram entries in OilProfile.

oil_profile_stamp ()

unsigned long       oil_profile_stamp                   (void);

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

oil_profile_init ()

void                oil_profile_init                    (OilProfile *prof);

Initializes a profiling structure.

oil_profile_stop_handle ()

void                oil_profile_stop_handle             (OilProfile *prof);

Handles post-processing of a single profiling run.

FIXME: need more info

oil_profile_get_ave_std ()

void                oil_profile_get_ave_std             (OilProfile *prof,
                                                         double *ave_p,
                                                         double *std_p);

Calculates the average and standard deviation of a number of profiling runs, and places the results in the locations provided by ave_p and std_p. Either ave_p and std_p may be NULL, in which case the values will not be written.

oil_profile_start()

#define             oil_profile_start(x)

Starts a profiling run by obtaining a timestamp via oil_profile_stamp() and writing it into x.

oil_profile_stop()

#define             oil_profile_stop(x)

Stops a profiling run by obtaining a timestamp via oil_profile_stamp() and writing it into x. It then calls oil_profile_stop_handle() to handle post-processing of the profiling run.
