Typedef

libndtypes has a global lookup table for type aliases. These aliases are treated as nominal types in pattern matching.

int ndt_init(ndt_context_t *ctx);

This function must be called at program start to initialize the typedef table.

int ndt_typedef(const char *name, ndt_t *type, ndt_context_t *ctx);

Create a nominal type alias for type. The function steals the type argument.
