3972 * Boilerplate macros for initializing and accessing interpreter-local
3973 * data from C. All statics in extensions should be reworked to use
3974 * this, if you want to make the extension thread-safe. See ext/re/re.xs
3975 * for an example of the use of these macros, and perlxs.pod for more.
3977 * Code that uses these macros is responsible for the following:
3978 * 1. #define MY_CXT_KEY to a unique string, e.g.
3979 * "DynaLoader::_guts" XS_VERSION
3980 * 2. Declare a typedef named my_cxt_t that is a structure that contains
3981 * all the data that needs to be interpreter-local.
3982 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
3983 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
3984 * (typically put in the BOOT: section).
3985 * 5. Use the members of the my_cxt_t structure everywhere as
3987 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
3991 #if defined(PERL_IMPLICIT_CONTEXT)
3993 /* This must appear in all extensions that define a my_cxt_t structure,
