Timers

Name

Timers -- functions to time operations.

Synopsis


#include <glib.h>


struct      GTimer;
GTimer*     g_timer_new                     (void);
void        g_timer_start                   (GTimer *timer);
void        g_timer_stop                    (GTimer *timer);
gdouble     g_timer_elapsed                 (GTimer *timer,
                                             gulong *microseconds);
void        g_timer_reset                   (GTimer *timer);
void        g_timer_destroy                 (GTimer *timer);

Description

Timers can be used to time operations, in a similar way to a stopwatch. Call g_timer_new() to create the timer, g_timer_start() to start it, g_timer_elapsed() to determine the time which has elapsed since the timer was started, and g_timer_stop() to stop the timer.

Details

struct GTimer

struct GTimer;

An opaque data structure which holds the timer information.

g_timer_new ()

GTimer*     g_timer_new                     (void);

Creates a new timer.

Returns :the new timer.

g_timer_start ()

void        g_timer_start                   (GTimer *timer);

Starts the timer.

timer :the timer.

g_timer_stop ()

void        g_timer_stop                    (GTimer *timer);

Stops the timer.

timer :the timer.

g_timer_elapsed ()

gdouble     g_timer_elapsed                 (GTimer *timer,
                                             gulong *microseconds);

timer :the timer.
microseconds :if non-NULL, this will be set to the microseconds component of the elapsed time (it does not include the number of seconds elapsed).
Returns :the elapsed time in seconds, as a double.

g_timer_reset ()

void        g_timer_reset                   (GTimer *timer);

Resets the elapsed time to 0, leaving the timer running.

timer :the timer.

g_timer_destroy ()

void        g_timer_destroy                 (GTimer *timer);

Destroys the timer, freeing the memory allocated for it.

timer :the timer.
