+// is split into a CRYPTO_once_t-guarded initializer in the module and
+// unhashed, non-module accessor functions to space reserved in the BSS. The
+// method table is initialized by a caller-supplied function which takes a
+// parameter named |out| of type |type|*. The caller should follow the macro
+// invocation with the body of this function:

+//       out->block_size = 64;
+//       out->ctx_size = sizeof(MD4_CTX);
+//     }
+//
+// This mechanism does not use a static initializer because their execution
+// order is undefined. See FIPS.md for more details.
