5297 * Boilerplate macros for initializing and accessing interpreter-local

5301 * and perlxs.pod for more.

5305 * "DynaLoader::_guts" XS_VERSION
f16dd614 5306 * XXX in the current implementation, this string is ignored.
89ca4ac7
JH		 5307 * 2. Declare a typedef named my_cxt_t that is a structure that contains
5308 * all the data that needs to be interpreter-local.
5309 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
5310 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
5311 * (typically put in the BOOT: section).
5312 * 5. Use the members of the my_cxt_t structure everywhere as
5313 * MY_CXT.member.
5314 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
5315 * access MY_CXT.
