cpc_event_diff
cpc_event_diff(3CPC) cpc_event_diff(3CPC)
NAME
cpc_event_diff, cpc_event_accum - simple difference and accumulate operations
SYNOPSIS
cc [ flag... ] file... -lcpc [ library... ]
#include <libcpc.h>
void cpc_event_accum(cpc_event_t *accum, cpc_event_t *event);
void cpc_event_diff(cpc_event_t *diff, cpc_event_t *after, cpc_event_t *before);
The cpc_event_accum() and cpc_event_diff() functions perform common accumulate and difference operations on cpc_event(3CPC) data struc-
tures. Use of these functions increases program portability, since structure members are not referenced directly .
cpc_event_accum()
The cpc_event_accum() function adds the ce_pic fields of event into the corresponding fields of accum. The ce_hrt field of accum is set to
the later of the times in event and accum.
SPARC:
The function adds the contents of the ce_tick field of event into the corresponding field of accum.
:
The function adds the contents of the ce_tsc field of event into the corresponding field of accum.
cpc_event_diff()
The cpc_event_diff() function places the difference between the ce_pic fields of after and before and places them in the corresponding
field of diff. The ce_hrt field of diff is set to the ce_hrt field of after.
SPARC:
Additionally, the function computes the difference between the ce_tick fields of after and before, and places it in the corresponding field
of diff.
:
Additionally, the function computes the difference between the ce_tsc fields of after and before, and places it in the corresponding field
of diff.

The cpc_event_accum() and cpc_event_diff() functions exist for binary compatibility only. Source containing these functions will not com-
pile. These functions are obsolete and might be removed in a future release. Applications should use cpc_buf_add(3CPC) and
cpc_buf_sub(3CPC) instead.
