Detailed Description

Here we implement types and functions for __timer functions

Version:

1.0.1

History:

• 2006-01-25
  • Fix compilation errors on sun, change includes accordingly and code
• 2005-05-31
  • Eliminate the definition of EGwallClockTimer_t and replace it by a macro definition that replace it by EGtimer_t.
• 2004-01-20
  • Add a 'wall clock' __timer (Renan-Marcos) type and functions
• 2003-05-08
  • First Implementation

Note:

Up to now, this code will only work on linux machines, and maybe on unix/posix systems.

Define Documentation

#define EGtimerReset

(

__timer

)

({(__timer)->time = 0;})

this function reset the accumulated time to zero

Examples:

eg_dijkstra.ex.c, eg_ehash.ex.c, eg_maxclosure.ex.c, eg_min_cut.ex.c, eg_push_relabel.ex.c, eg_raset.ex.c, and eg_slk.ex.c.

#define EGtimerStart

(

__timer

)

({(__timer)->stime = __EGzeit();})

Set a new starting time for the __timer.

Parameters:

__timer

pointer to a EGtimer_t structure.

Returns:

starting time (in seconds), and the type is a double.

Examples:

eg_dijkstra.ex.c, eg_ehash.ex.c, eg_maxclosure.ex.c, eg_min_cut.ex.c, eg_push_relabel.ex.c, eg_raset.ex.c, and eg_slk.ex.c.

Referenced by main().

#define EGtimerStop

(

__timer

)

({(__timer)->time += __EGzeit() - (__timer)->stime;})

Stop a 'running' __timer and accumulate the run time.

Returns:

the time elapsed since the last 'start' call (in seconds).

Examples:

eg_dijkstra.ex.c, eg_ehash.ex.c, eg_maxclosure.ex.c, eg_min_cut.ex.c, eg_push_relabel.ex.c, eg_raset.ex.c, and eg_slk.ex.c.

#define EGwallClockTimer_t   EGtimer_t

This is done for backward compability, we used to define EGwallClockTimer_t just as the normal __timer, so in reality we don't need another type, but keep the name so that older code depending on this still compiles.

Definition at line 99 of file eg_timer.h.

#define EGwallClockTimerReset

(

__timer

)

EGtimerReset(__timer)

Reset the accumulated time to zero.

Definition at line 129 of file eg_timer.h.

#define EGwallClockTimerStart

(

__timer

)

({(__timer)->stime = time(0);})

Set the starting time the current (wall) time.

Returns:

the current wall time.

Definition at line 119 of file eg_timer.h.

#define EGwallClockTimerStop

(

__timer

)

Value:

({\
  (__timer)->time += difftime(time(0),(__timer)->stime);})

Stop a 'running' __timer and accumulate the (wall) runing time.

Returns:

the wall time elapsed since the last initialization.
