4394 * Boilerplate macros for initializing and accessing interpreter-local
4395 * data from C. All statics in extensions should be reworked to use
4396 * this, if you want to make the extension thread-safe. See ext/re/re.xs
9f650e94 4397 * for an example of the use of these macros, and perlxs.pod for more.

JH		 4400 * 1. #define MY_CXT_KEY to a unique string, e.g.
4401 * "DynaLoader::_guts" XS_VERSION
89ca4ac7
JH		 4402 * 2. Declare a typedef named my_cxt_t that is a structure that contains
4403 * all the data that needs to be interpreter-local.
4404 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
4405 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
4406 * (typically put in the BOOT: section).
4407 * 5. Use the members of the my_cxt_t structure everywhere as
4408 * MY_CXT.member.
4409 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
4410 * access MY_CXT.
