Occasion variables are thread-safe should they behave correctly when accessed from multiple threads, whatever the scheduling or interleaving with the execution of Those people threads via the runtime ecosystem, and without any further synchronization or other coordination around the part of the contacting code.
But for UP (and possibly MP), If a timer interrupt (or IPI for SMP) fires Within this small window of LDREX and STREX, Exception handler executes probably modifications cpu context and returns to The brand new undertaking, on the other hand the surprising element comes in now, it executes 'CLREX' and therefore removing any exclusive lock held by past thread. So how greater is making use of LDREX and STREX than LDR and STR for atomicity on a UP process ?
So Except you presently recognize that and why you need atomic functions, the type might be not of much use to suit your needs.
"Ham and eggs" only jumped by 1 Although 2 people voted for it! This is often Evidently not what we required. If only there was an atomic Procedure "increment if it exists or create a new document"... for brevity, let us simply call it "upsert" (for "update or insert")

Should they strike simultaneously, the reader thread is sure to get among the list of two values: possibly ahead of the transform or following the transform.
