*/
/** \file
* \ingroup DNA
*
* This API provides direct access to DNA default structs
* to avoid duplicating values for initialization, versioning and RNA.
* This allows DNA default definitions to be defined in a single header along side the types.
* So each `DNA_{name}_types.h` can have an optional `DNA_{name}_defaults.h` file along side it.
*
* Defining the defaults is optional since it doesn't make sense for some structs to have defaults.
*
* To create these defaults there is a GDB script which can be handy to get started:
* `./source/tools/utils/gdb_struct_repr_c99.py`
*
* Magic numbers should be replaced with flags before committing.
*
* The main functions to access these are:
* - #DNA_struct_default_get
* - #DNA_struct_default_alloc
*
* These access the struct table #DNA_default_table using the struct number.
*
* \note Struct members only define their members (pointers are left as NULL set).
