I am trying to use the sleep function in leulieu of delay(); butdelay(), but when I include sleep();sleep(), I get Sweep.cpp:60:10: error: ‘sleep’ was not declared in this scopeSweep.cpp:60:10: error: ‘sleep’ was not declared in this scope

I read some place, about #include <avr/sleep.h>#include <avr/sleep.h> but that is a fail.

#include <avr/sleep.h>
void setup() { 
}
void loop() {
 digitalWrite(13, HIGH); // set the LED on
 sleep(1); // wait for a second
 digitalWrite(13, LOW); // set the LED off
 sleep(1000); // wait for a second
}

I was able to locate sleep.h,sleep.h:

$ locate sleep.h | grep avr
/usr/lib/avr/include/avr/sleep.h

soSo then I started reading avr/sleep.havr/sleep.h, and it seems like ImI'm doing it right, according to the examples. SoSo, why might this be failing?
