On UNIX systems you can use the uname(3) system call. See

$ man 3 uname

Example:

#include 
#include 

int main()

    uname(&un);
    printf("sysname: %s\nnodename: %s\nrelease: %s\nversion: %s\nmachine: %s\n",
        un.sysname, un.nodename, un.release, un.version, un.machine);
}

On Mac OS X 10.8.5 I get "9.8.0" as the release number. See list of releases. 10.0 is Mac OS X 10.6, 10.2.0 is Mac OS X 10.6.2.
