atomic read and increment question

Hello, I looked through the documentation for atomic operations but couldn't find out the api for following operation: x = 1; temp = atomic_read_increment(x); so basically this will read the old value of x in temp and then increment x. so temp = 1 and x = 2. Is this api already available?

atomic read and increment question

Hello, I looked through the documentation for atomic operations but couldn't find out the api for following operation: x = 1; temp = atomic_read_increment(x); so basically this will read the old value of x in temp and then increment x. so temp = 1 and x = 2. Is this api already available?
