5102 Some of these reference functions in the perl object files, and some
5103 compilers aren't smart enough to eliminate unused static inline
5104 functions, so including this file in source code can cause link errors
5105 even if the source code uses none of the functions. Hence including these
5106 can be be suppressed by setting PERL_NO_INLINE_FUNCTIONS. Doing this will
5107 (obviously) result in unworkable XS code, but allows simple probing code
5108 to continue to work, because it permits tests to include the perl headers
5109 for definitions without creating a link dependency on the perl library
5110 (which may not exist yet).

5476 * Boilerplate macros for initializing and accessing interpreter-local
5477 * data from C. All statics in extensions should be reworked to use
7588b095
JH		 5478 * this, if you want to make the extension thread-safe. See

5480 * and perlxs.pod for more.
89ca4ac7

5482 * Code that uses these macros is responsible for the following:
43a739c2
JH		 5483 * 1. #define MY_CXT_KEY to a unique string, e.g.
5484 * "DynaLoader::_guts" XS_VERSION
f16dd614 5485 * XXX in the current implementation, this string is ignored.
89ca4ac7
JH		 5486 * 2. Declare a typedef named my_cxt_t that is a structure that contains
5487 * all the data that needs to be interpreter-local.
5488 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
5489 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
5490 * (typically put in the BOOT: section).
5491 * 5. Use the members of the my_cxt_t structure everywhere as
5492 * MY_CXT.member.
5493 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
5494 * access MY_CXT.
