CONDITIONAL VARIABLE Meaning and
Definition
-
A conditional variable, also known as a condition variable or condition, is a synchronization primitive used in concurrent programming. It is a tool that allows threads or processes to wait for a certain condition to become true before proceeding with their execution.
In a multi-threaded environment, different threads may need to communicate or coordinate their activities with each other. A conditional variable provides a mechanism for threads to wait for a specific state to be reached, allowing them to proceed only when the desired condition is met. It is commonly used in situations where one or more threads need to wait for the completion of an operation performed by another thread.
A conditional variable typically consists of a queue and a lock. The lock is used to protect access to the queue and ensure that only one thread can modify it at a time. When a thread needs to wait for a condition, it releases the lock and enters a waiting state. Other threads can then acquire the lock and modify the state of the condition. When the desired condition is met, the thread is awakened and reacquires the lock before continuing its execution.
Conditional variables are essential in preventing busy waiting, where a thread continuously checks for a condition in a tight loop, wasting CPU resources. Instead, threads can use conditional variables to efficiently wait for a condition to become true, minimizing resource consumption and improving overall system performance.
