Semaphored: meaning, definitions and examples
🚦
semaphored
[ˈsɛm.ə.fɔrd ]
Definition
programming term
Semaphore is a synchronization mechanism that is used to control access to a common resource in concurrent programming environments. Semaphores can be thought of as signaling devices that enable threads to communicate about the availability of resources. In practice, they are often used to manage access to shared data, preventing race conditions and ensuring data integrity. When a process wants to access a resource, it must acquire the semaphore; if the semaphore is already taken, the process is blocked until it becomes available again.
Synonyms
coordinate, signal, synchronize.
Examples of usage
- The thread was semaphores to wait for the resource.
