6059 * Boilerplate macros for initializing and accessing interpreter-local
6060 * data from C. All statics in extensions should be reworked to use
6061 * this, if you want to make the extension thread-safe. See
6062 * ext/XS/APItest/APItest.xs for an example of the use of these macros,
6063 * and perlxs.pod for more.
6065 * Code that uses these macros is responsible for the following:
6066 * 1. #define MY_CXT_KEY to a unique string, e.g.
6067 * "DynaLoader::_guts" XS_VERSION
6068 * XXX in the current implementation, this string is ignored.
6069 * 2. Declare a typedef named my_cxt_t that is a structure that contains
6070 * all the data that needs to be interpreter-local.
6071 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
6072 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
6073 * (typically put in the BOOT: section).
6074 * 5. Use the members of the my_cxt_t structure everywhere as
6076 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
6080 #if defined(PERL_IMPLICIT_CONTEXT)
