5094 | * Boilerplate macros for initializing and accessing interpreter-local | |
5095 | * data from C. All statics in extensions should be reworked to use | |
5096 | * this, if you want to make the extension thread-safe. See ext/re/re.xs | |

89ca4ac7 JH |
5098 | * |
5099 | * Code that uses these macros is responsible for the following: | |
43a739c2 JH |
5100 | * 1. #define MY_CXT_KEY to a unique string, e.g. |
5101 | * "DynaLoader::_guts" XS_VERSION | |
f16dd614 | 5102 | * XXX in the current implementation, this string is ignored. |
89ca4ac7 JH |
5103 | * 2. Declare a typedef named my_cxt_t that is a structure that contains |
5104 | * all the data that needs to be interpreter-local. | |
5105 | * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t. | |
5106 | * 4. Use the MY_CXT_INIT macro such that it is called exactly once | |
5107 | * (typically put in the BOOT: section). | |
5108 | * 5. Use the members of the my_cxt_t structure everywhere as | |
5109 | * MY_CXT.member. | |
5110 | * 6. Use the dMY_CXT macro (a declaration) in all the functions that | |
5111 | * access MY_CXT. | |
