| /* |
| * MAKE_DECODER is the single driver for creating OSSL_DISPATCH tables. |
| * It takes the following arguments: |
| * |
| * keytype_name The implementation key type as a string. |
| * keytype The implementation key type. This must correspond exactly |
| * to our existing keymgmt keytype names... in other words, |
| * there must exist an ossl_##keytype##_keymgmt_functions. |
| * type The type name for the set of functions that implement the |
| * decoder for the key type. This isn't necessarily the same |
| * as keytype. For example, the key types ed25519, ed448, |
| * x25519 and x448 are all handled by the same functions with |
| * the common type name ecx. |
| * kind The kind of support to implement. This translates into |
| * the DO_##kind macros above, to populate the keytype_desc_st |
| * structure. |
