NAME

insertinit, insertsort, get_results, set_results, save_median, save_minimum - the lmbench results subsystem

SYNOPSIS

#include ``lmbench.h''

#define TRIES 11

typedef struct { uint64 u, n } value_t;

typedef struct { int N; value_t v[TRIES]; } result_t;

int sizeof_result(int N)

void insertinit(result_t *r)

void insertsort(uint64 u, uint64 n, result_t *r)

result_t* get_results()

void set_results(result_t *r)

void save_median()

void save_minimum()

DESCRIPTION

These routines provide some simple data management functionality. In most cases, you will not need these routines.

The current timing results can be accessed using the routines in timing(3). The current timing results may be modified using save_median and save_minimum.

int sizeof_result(int N)

returns the number of bytes to allocate for a result_t which contains N results.

void insertinit(result_t *r)

initializes the results array.

void insertsort(uint64 u, uint64 n, result_t *r)

insert u and n into r. Results are sorted in decreasing order by u/n.

void get_results(result_t *r)

get a copy of the current results.

void set_results(result_t *r)

save a copy r as the current results.

void save_median()

sets the timing results to the median of the current results.

void save_minimum()

sets the timing restuls to the minimum of the current results.

Results are sorted in ascending order, so the minimum value is at TRIES-1 and the maximum value is at 0.

FUTURES

Development of lmbench is continuing.
