4809 * Boilerplate macros for initializing and accessing interpreter-local
4810 * data from C. All statics in extensions should be reworked to use

4812 * for an example of the use of these macros, and perlxs.pod for more.
4814 * Code that uses these macros is responsible for the following:
4815 * 1. #define MY_CXT_KEY to a unique string, e.g.
4816 * "DynaLoader::_guts" XS_VERSION
4817 * 2. Declare a typedef named my_cxt_t that is a structure that contains
4818 * all the data that needs to be interpreter-local.
4819 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
4820 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
4821 * (typically put in the BOOT: section).
4822 * 5. Use the members of the my_cxt_t structure everywhere as
4824 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
