sleep(1.5); //Secs
BCM2835 Library
The bcm2835 library by Mike McCauley includes some useful delay functions:
bcm2835_delayMicroseconds(100); //Sleep occasionally so scheduler doesn't penalise us (THIS REQUIRES -lrt ADDING AS A COMPILER FLAG OR IT WILL CAUSE LOCK UP)
bcm2835_delay(1); //Delay in mS

Are the sleep / usleep functions blocking?
I like that they are part of a library that is part of RaspbianOS!
I have just started trying out C on the RPi, and am still checking out libraries. First lesson has been to try and stick to the standard libaries in /usr/include !
Thanks
