   8  * Version 2.x, Copyright (C) 2001, Paul Marquess.

  10  * This code may be used and distributed under the same license as any
  11  * version of Perl.
  12  *
  13  * This version of ppport.h is designed to support operation with Perl
  14  * installations back to 5.004, and has been tested up to 5.8.1.
  15  *
  16  * If this version of ppport.h is failing during the compilation of this
  17  * module, please check if a newer version of Devel::PPPort is available
  18  * on CPAN before sending a bug report.
  19  *
  20  * If you are using the latest version of Devel::PPPort and it is failing
  21  * during compilation of this module, please send a report to perlbug@perl.com
  22  *
  23  * Include all following information:
  24  *
  25  *  1. The complete output from running "perl -V"
  26  *
  27  *  2. This file.
  28  *
  29  *  3. The name & version of the module you were trying to build.
  30  *
  31  *  4. A full log of the build that failed.
  32  *
  33  *  5. Any other information that you think could be relevant.
  34  *
  35  *
  36  * For the latest version of this code, please retreive the Devel::PPPort
  37  * module from CPAN.

  42  * In order for a Perl extension module to be as portable as possible
  43  * across differing versions of Perl itself, certain steps need to be taken.
  44  * Including this header is the first major one, then using dTHR is all the
  45  * appropriate places and using a PL_ prefix to refer to global Perl
  46  * variables is the second.

  51 /* If you use one of a few functions that were not present in earlier
  52  * versions of Perl, please add a define before the inclusion of ppport.h
  53  * for a static include, or use the GLOBAL request in a single module to
  54  * produce a global definition that can be referenced from the other
  55  * modules.

  63 /* To verify whether ppport.h is needed for your module, and whether any
  64  * special defines should be used, ppport.h can be run through Perl to check
  65  * your source code. Simply say:
  66  *
  67  *      perl -x ppport.h *.c *.h *.xs foo/bar*.c [etc]
  68  *
  69  * The result will be a list of patches suggesting changes that should at
  70  * least be acceptable, if not necessarily the most efficient solution, or a
  71  * fix for all possible problems. It won't catch where dTHR is needed, and
  72  * doesn't attempt to account for global macro or function definitions,
  73  * nested includes, typemaps, etc.
  74  *
  75  * In order to test for the need of dTHR, please try your module under a
  76  * recent version of Perl that has threading compiled-in.

 423  * for an example of the use of these macros.
 424  *
 425  * Code that uses these macros is responsible for the following:
 426  * 1. #define MY_CXT_KEY to a unique string, e.g. "DynaLoader_guts"
 427  * 2. Declare a typedef named my_cxt_t that is a structure that contains
 428  *    all the data that needs to be interpreter-local.
 429  * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
 430  * 4. Use the MY_CXT_INIT macro such that it is called exactly once
 431  *    (typically put in the BOOT: section).
 432  * 5. Use the members of the my_cxt_t structure everywhere as
 433  *    MY_CXT.member.
 434  * 6. Use the dMY_CXT macro (a declaration) in all the functions that
 435  *    access MY_CXT.
