CPU Performance Counters Library Functions   cpceventdiff(3CPC)



NAME
     cpceventdiff,  cpceventaccum  -  simple  difference  and
     accumulate operations

SYNOPSIS
     cc [ flag... ] file... -lcpc [ library... ]
     #include 

     void cpceventaccum(cpceventt *accum, cpceventt *event);


     void cpceventdiff(cpceventt *diff, cpceventt *after,
          cpceventt *before);


DESCRIPTION
     The cpceventaccum() and cpceventdiff()  functions   per-
     form   common   accumulate   and  difference  operations  on
     cpcevent(3CPC) data  structures.  Use  of  these  functions
     increases  program  portability, since structure members are
     not referenced directly .

  cpceventaccum()
     The cpceventaccum() function adds  the  cepic  fields  of
     event  into  the  corresponding  fields of accum. The cehrt
     field of accum is set to the later of the times in event and
     accum.

  SPARC:
     The function adds the contents of the cetick field of event
     into the corresponding field of accum.

  x86:
     The function adds the contents of the cetsc field of  event
     into the corresponding field of accum.

  cpceventdiff()
     The cpceventdiff() function places the difference  between
     the cepic fields of after and before and places them in the
     corresponding field of diff. The cehrt field of diff is set
     to the cehrt field of after.

  SPARC:
     Additionally, the function computes the  difference  between
     the cetick fields of after and before, and places it in the
     corresponding field of diff.

  x86:
     Additionally, the function computes the  difference  between
     the  cetsc fields of after and before, and places it in the
     corresponding field of diff.

NOTES
     The cpceventaccum() and cpceventdiff()  functions  exist
     for binary compatibility only. Source containing these func-
     tions will not compile. These  functions  are  obsolete  and
     might  be  removed  in a future release. Applications should
     use cpcbufadd(3CPC) and cpcbufsub(3CPC) instead.
