Description
GTimer records a start time, and counts microseconds elapsed since that time. This is done somewhat differently on different platforms, and can be tricky to get exactly right, so GTimer provides a portable/convenient interface.
Functions
g_timer_new ()
GTimer *
g_timer_new (void
);
Creates a new timer, and starts timing (i.e. g_timer_start()
is
implicitly called for you).
g_timer_start ()
void
g_timer_start (GTimer *timer
);
Marks a start time, so that future calls to g_timer_elapsed()
will
report the time since g_timer_start()
was called. g_timer_new()
automatically marks the start time, so no need to call
g_timer_start()
immediately after creating the timer.
g_timer_stop ()
void
g_timer_stop (GTimer *timer
);
Marks an end time, so calls to g_timer_elapsed()
will return the
difference between this end time and the start time.
g_timer_continue ()
void
g_timer_continue (GTimer *timer
);
Resumes a timer that has previously been stopped with
g_timer_stop()
. g_timer_stop()
must be called before using this
function.
Since: 2.4
g_timer_elapsed ()
gdouble g_timer_elapsed (GTimer *timer
,gulong *microseconds
);
If timer
has been started but not stopped, obtains the time since
the timer was started. If timer
has been stopped, obtains the
elapsed time between the time it was started and the time it was
stopped. The return value is the number of seconds elapsed,
including any fractional part. The microseconds
out parameter is
essentially useless.
g_timer_reset ()
void
g_timer_reset (GTimer *timer
);
This function is useless; it's fine to call g_timer_start()
on an
already-started timer to reset the start time, so g_timer_reset()
serves no purpose.
