4001 * Boilerplate macros for initializing and accessing interpreter-local
4002 * data from C. All statics in extensions should be reworked to use
4003 * this, if you want to make the extension thread-safe. See ext/re/re.xs
9f650e94 4004 * for an example of the use of these macros, and perlxs.pod for more.
89ca4ac7
JH		 4005 *
4006 * Code that uses these macros is responsible for the following:
43a739c2
JH		 4007 * 1. #define MY_CXT_KEY to a unique string, e.g.
4008 * "DynaLoader::_guts" XS_VERSION
89ca4ac7
JH		 4009 * 2. Declare a typedef named my_cxt_t that is a structure that contains
4010 * all the data that needs to be interpreter-local.
4011 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
4012 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
4013 * (typically put in the BOOT: section).
4014 * 5. Use the members of the my_cxt_t structure everywhere as
4015 * MY_CXT.member.
4016 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
4017 * access MY_CXT.
