4013 * Boilerplate macros for initializing and accessing interpreter-local
4014 * data from C. All statics in extensions should be reworked to use
4015 * this, if you want to make the extension thread-safe. See ext/re/re.xs

4020 * "DynaLoader::_guts" XS_VERSION
89ca4ac7
JH		 4021 * 2. Declare a typedef named my_cxt_t that is a structure that contains
4022 * all the data that needs to be interpreter-local.
4023 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
4024 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
4025 * (typically put in the BOOT: section).
4026 * 5. Use the members of the my_cxt_t structure everywhere as
4027 * MY_CXT.member.
4028 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
4029 * access MY_CXT.
