Detailed Description

Atomic operations.

Atomic operations are used to perform certain operations in a way that is guaranteed to be indivisible and not subject to interruption by other threads. This is particularly useful in multithreaded programming to avoid race conditions and ensure correct behavior when multiple threads are concurrently accessing shared data.

Macro Definition Documentation

◆ atomicFetchAdd32

#define atomicFetchAdd32	(		memory,
			value ) InterlockedExchangeAdd(memory, value)

Atomically adds the value to the variable that memory points to.

Result is stored in the address that is specified by memory.

Parameters

[in]	memory	pointer of a variable to which value is to be added.
	value	variable whose value is to be added to the variable that memory points to.

Returns: The initial value of the variable that memory points to.

◆ atomicFetchAdd64

#define atomicFetchAdd64	(		memory,
			value ) InterlockedExchangeAdd64(memory, value)
