# Time routines

These functions are declared in the main Allegro header file:

     #include <allegro5/allegro.h>

# ALLEGRO_TIMEOUT

    typedef struct ALLEGRO_TIMEOUT ALLEGRO_TIMEOUT;

Represent a timeout value. The size of the structure is known so can be statically allocated. The contents are private.

See also: al_init_timeout

# al_get_time

    double al_get_time(void)

Return the number of seconds since the Allegro library was initialised. The return value is undefined if Allegro is uninitialised. The resolution depends on the used driver, but typically can be in the order of microseconds.

# al_current_time

Alternate spelling of al_get_time.

# al_init_timeout

    void al_init_timeout(ALLEGRO_TIMEOUT *timeout, double seconds)

Set timeout value of some number of seconds after the function call.

See also: ALLEGRO_TIMEOUT, al_wait_for_event_until

# al_rest

    void al_rest(double seconds)

Waits for the specified number seconds. This tells the system to pause the current thread for the given amount of time. With some operating systems, the accuracy can be in the order of 10ms. That is, even

    al_rest(0.000001)

might pause for something like 10ms. Also see the section on easier ways to time your program without using up all CPU.
