c++ - Atomic increment on mac OS X -

-

I have googled for atomic increments and decrease operators on Mac OS X and found "OSAtomic.h" but it seems That you can use it only in the kernel space.

told me on a cross-platform, in which they use assembly or mutes on OS X (as far as I am among the ifdefs).

Is there nothing like InterlockedDecrement or atomic_dec () on OS X?

Do you think OSAtmic is the only kernel space? The following compile and works fine. 

  #include & lt; Libkern / OSAtomic.h> # Include & lt; Stdio.h & gt; Int main (int argc, char ** argv) {int32_t foo = 1; OSAtomicDecrement32 (& amp; foo); Printf ("% d \ n", foo); Return 0; }

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
