These functions are declared in the main Allegro header file:
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
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.
void al_init_timeout(ALLEGRO_TIMEOUT *timeout, double seconds)
Set timeout value of some number of seconds after the function call.

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
might pause for something like 10ms. Also see the section
