=head1 DESCRIPTION
variable is modified by CRYPTO_atomic_add() then CRYPTO_atomic_add() must
be the only way that the variable is modified.
-=item *
-
-CRYPTO_atomic_read() atomically reads B<val> and returns the result of
-the operation in B<ret>. B<lock> will be locked, unless atomic operations
-are supported on the specific platform.
-
-=item *
-
-CRYPTO_atomic_write() atomically writes B<n> to B<val>. B<lock> will be
-locked, unless atomic operations are supported on the specific platform.
