The atomic_inc family of functions increment (by one) the variable referenced by ptr in an
The *_nv() variants of these functions return the new value.
The 64-bit variants of these functions are available only on platforms that can support
atomic 64-bit memory access. Applications can check for the availability of 64-bit atomic
memory operations by testing if the pre-processor macro __HAVE_ATOMIC64_OPS is defined.
The atomic_inc functions first appeared in NetBSD 5.0.
