Subject: 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?

Thanks,
