Readers-writer lock - Wikipedia
https://en.wikipedia.org/wiki/Readers%E2%80%93writer_lock
In computer science, a readers-writer (single-writer lock, a multi-reader lock, a push lock, or an MRSW lock) is a synchronization primitive that solves one of the readers-writers problems. An RW lock allows concurrent access for read-only operations, while write operations require exclusive access.

A more efficient writer-preferring RW lock
https://eli.thegreenplace.net/2019/implementing-reader-writer-locks/
Reader-writer locks (RW locks from here on) were created from the observation that multiple threads can read shared data concurrently, as long as no one is modifying that data while it's being read.

Locks are primitives that provide mutual exclusion that allow data structures to remain in consistent states. Without locking, multiple threads of execution may simultaneously modify a data structure.
Lockless programming with atomics in C++ 11 vs. mutex and RW-locks
