recursion - What exactly is a reentrant function? - Stack Overflow
WEBThe simplest form of a reentrant function is something that operates exclusively on the arguments passed and constant values. Anything else takes special handling or, often, is not reentrant. And of course the arguments must not reference mutable globals.
Reentrancy (computing) - Wikipedia
WEBReentrant code is designed to be safe and predictable when multiple instances of the same function are called simultaneously or in quick succession. A computer program or subroutine is called reentrant if multiple invocations can safely run concurrently on multiple processors , or if on a single-processor system its execution can be …

What is the Re-entrant lock and concept in general?
WEBDec 15, 2015 · A reentrant lock is one where a process can claim the lock multiple times without blocking on itself. It's useful in situations where it's not easy to keep track of whether you've already grabbed a lock. If a lock is non re-entrant you could grab the lock, then block when you go to grab it again, effectively deadlocking your own process.

Binary Semaphore vs Reentrant Lock | Baeldung
WEBJan 8, 2024 · A reentrant lock is a mutual exclusion mechanism that allows threads to reenter into a lock on a resource (multiple times) without a deadlock situation. A thread entering into the lock increases the hold count by one every time. Similarly, the hold count decreases when unlock is requested.
What is Reentrant Kernel? - GeeksforGeeks
WEBFeb 4, 2022 · Reentrant Kernel: In kernel mode, a reentrant kernel allows processes (or, more precisely, their corresponding kernel threads) to give up the CPU. They have no effect on other processes entering kernel mode. Multiple processor systems may be scheduled together in the case of single-processor systems. Example:
