-/*!
- * \brief Simple write-once allocation-optimal dynamic array.
- *
- * Include it into your .c file
- *
- * prefix - identifier prefix, e.g. ptr -> struct ptr_dynarray, ptr_dynarray_add(), ...
- * ntype - data type to be stored. Let it be a number, pointer or small struct
- * initial_capacity - how many data items will be allocated on stack and copied with assignment
- *
- * prefix_dynarray_add() - add a data item
- * prefix_dynarray_fix() - call EVERYTIME the array is copied from some already invalid stack
- * prefix_dynarray_free() - call EVERYTIME you dismiss all copies of the array
- *
