4coder/4coder_api_transition_30_31.cpp

/*
 * Helpers for the API transition from 4.0.30 to 4.0.31
 *
 * In order to keep your layer on the old API you don't have to do anything, this provides wrappers
 *  idential to the 4.0.30 API.
 * In order to transition your entire layer over to the 4.0.31 API define 'REMOVE_TRANSITION_HELPER' and fix errors.
 * Or you can do it step by step by removing a few wrappers at a time.
 * This transition helper will be removed in a future version so it is recommended to get off sooner or laster.
 *
 * Tips on transitioning:
*
* Wrather than just try to inline this code everywhere, you can simplify things quite a lot by storing references
* to buffers and views and Buffer_ID and View_ID instead of Buffer_Summary and View_Summary.
 * Just get the summaries when you need information in those structures.
 *
 * You will make your code simpler if you stick to String as much as possible, but whenever you want to you can switch
 * to any string type you have to String by calling make_string(char_ptr, length) or make_string_slowly(null_terminated_c_str).
 * To pull the char ptr and length out of a String named "string": string.str and str.size.
 * If you need a null terminated string from a String use get_null_terminated in 4coder_helper.cpp
 *
