Introduction to Conditional Variables
Explore the concept of conditional variables and understand how they help threads wait efficiently for specific conditions in concurrent programs. This lesson explains why simple spinning is inefficient and introduces ways to put threads to sleep until conditions are met, improving synchronization.

Thus far you have developed the notion of a lock and seen how one can be properly built with the right combination of hardware and OS support. Unfortunately, locks are not the only primitives that are needed to build concurrent programs.
In particular, there are many cases where a thread wishes ...
