20 | # The generated pod consists of sections of related elements, functions, |
21 | # macros, and variables. The keys of %valid_sections give the current legal | |
22 | # ones. Just add a new key to add a section. | |
23 | # | |
24 | # Throughout the files read by this script are lines like | |
25 | # | |
26 | # =for apidoc_section Section Name | |
27 | # | |
28 | # "Section Name" (after having been stripped of leading space) must be one of | |
29 | # the legal section names, or an error is thrown. All API elements defined | |
30 | # between this line and the next 'apidoc_section' line will go into the | |
31 | # section "Section Name", sorted by dictionary order within it. perlintern | |
32 | # and perlapi are parallel documents, each potentially with a section "Section | |
33 | # Name". Each element is marked as to which document it goes into. If there | |
34 | # are none for a particular section in perlapi, that section is | |
35 | # omitted. | |
36 | # | |
37 | # Also, in .[ch] files, there may be | |
38 | # | |
39 | # =head1 Section Name | |
40 | # | |
41 | # lines in comments. These are also used by this program to switch to section | |
42 | # "Section Name". The difference is that if there are any lines after the | |
43 | # =head1, inside the same comment, and before any =for apidoc-ish lines, they | |
44 | # are used as a heading for section "Section Name" (in both perlintern and | |
45 | # perlapi). This includes any =head[2-5]. If more than one '=head1 Section | |
46 | # Name' line has content, they appear in the generated pod in an undefined | |
47 | # order. | |
48 | # | |
49 | # The next =head1, =for apidoc_section, or file end terminates what goes into | |
50 | # the current section | |
51 | # | |
52 | # The %valid_sections hash below also can have header content, which will | |
53 | # appear before any =head1 content. The hash can also have footer content | |
54 | # content, which will appear at the end of the section, after all the | |
55 | # elements. | |
56 | # | |
57 | # The lines that define the actual functions, etc are documented in embed.fnc, | |
58 | # because they have flags which must be kept in sync with that file. | |

6927cd44 KW |
148 | This is a list of those symbols that dont appear elsewhere in ths |
149 | document that indicate if the current platform has a certain | |
150 | capability. Their names all begin with C<HAS_>. Only those | |
151 | symbols whose capability is directly derived from the name are | |
152 | listed here. All others have their meaning expanded out elsewhere | |
153 | in this document. This (relatively) compact list is because we | |
154 | think that the expansion would add little or no value and take up | |
155 | a lot of space (because there are so many). If you think certain | |
156 | ones should be expanded, send email to | |
157 | L<perl5-porters@perl.org|mailto:perl5-porters@perl.org>. | |
00d68f0d KW |
158 | |
159 | Each symbol here will be C<#define>d if and only if the platform | |
160 | has the capability. If you need more detail, see the | |
6927cd44 KW |
161 | corresponding entry in F<config.h>. For convenience, the list is |
162 | split so that the ones that indicate there is a reentrant version | |
163 | of a capability are listed separately | |

183 | =head2 List of C<#include> needed symbols | |

185 | This list contains symbols that indicate if certain C<#include> | |
186 | files are present on the platform. If your code accesses the | |
187 | functionality that one of these is for, you will need to | |
188 | C<#include> it if the symbol on this list is C<#define>d. For | |

1447 | |X<Perl API> X<API> X<api> | |
1448 | | | |
b87d9527 KW |
1449 | |This file contains most of the documentation of the perl public API, as |
1450 | |generated by F<embed.pl>. Specifically, it is a listing of functions, | |
a026e430 KW |
1451 | |macros, flags, and variables that may be used by extension writers. Besides |
1452 | |L<perlintern> and F<config.h>, some items are listed here as being actually | |
1453 | |documented in another pod. | |
b87d9527 KW |
1454 | | |
1455 | |L<At the end|/Undocumented functions> is a list of functions which have yet | |
1456 | |to be documented. Patches welcome! The interfaces of these are subject to | |
1457 | |change without notice. | |
1458 | | | |
6927cd44 KW |
1459 | |Some of the functions documented here are consolidated so that a single entry |
1460 | |serves for multiple functions which all do basically the same thing, but have | |
1461 | |some slight differences. For example, one form might process magic, while | |
1462 | |another doesn't. The name of each variation is listed at the top of the | |
1463 | |single entry. But if all have the same signature (arguments and return type) | |
1464 | |except for their names, only the usage for the base form is shown. If any | |
1465 | |one of the forms has a different signature (such as returning C<const> or | |
1466 | |not) every function's signature is explicitly displayed. | |
7260d4ba | 1467 | | |
a026e430 KW |
1468 | |Anything not listed here or in the other mentioned pods is not part of the |
1469 | |public API, and should not be used by extension writers at all. For these | |
1470 | |reasons, blindly using functions listed in F<proto.h> is to be avoided when | |
1471 | |writing extensions. | |
6a4c4cd4 DM |
1472 | | |
1473 | |In Perl, unlike C, a string of characters may generally contain embedded | |
1474 | |C<NUL> characters. Sometimes in the documentation a Perl string is referred | |
1475 | |to as a "buffer" to distinguish it from a C string, but sometimes they are | |
1476 | |both just referred to as strings. | |
1477 | | | |
1478 | |Note that all Perl API global variables must be referenced with the C<PL_> | |
1479 | |prefix. Again, those not listed here are not to be used by extension writers, | |
1480 | |and can be changed or removed without notice; same with macros. | |
1481 | |Some macros are provided for compatibility with the older, | |
1482 | |unadorned names, but this support may be disabled in a future release. | |
1483 | | | |
1484 | |Perl was originally written to handle US-ASCII only (that is characters | |
1485 | |whose ordinal numbers are in the range 0 - 127). | |
1486 | |And documentation and comments may still use the term ASCII, when | |
1487 | |sometimes in fact the entire range from 0 - 255 is meant. | |
1488 | | | |
1489 | |The non-ASCII characters below 256 can have various meanings, depending on | |
1490 | |various things. (See, most notably, L<perllocale>.) But usually the whole | |
1491 | |range can be referred to as ISO-8859-1. Often, the term "Latin-1" (or | |
1492 | |"Latin1") is used as an equivalent for ISO-8859-1. But some people treat | |
1493 | |"Latin1" as referring just to the characters in the range 128 through 255, or | |
2de859ce | 1494 | |sometimes from 160 through 255. |
6a4c4cd4 DM |
1495 | |This documentation uses "Latin1" and "Latin-1" to refer to all 256 characters. |
1496 | | | |
1497 | |Note that Perl can be compiled and run under either ASCII or EBCDIC (See | |
1498 | |L<perlebcdic>). Most of the documentation (and even comments in the code) | |
1499 | |ignore the EBCDIC possibility. | |
1500 | |For almost all purposes the differences are transparent. | |
1501 | |As an example, under EBCDIC, | |
1502 | |instead of UTF-8, UTF-EBCDIC is used to encode Unicode strings, and so | |
1503 | |whenever this documentation refers to C<utf8> | |
1504 | |(and variants of that name, including in function names), | |
1505 | |it also (essentially transparently) means C<UTF-EBCDIC>. | |
1506 | |But the ordinals of characters differ between ASCII, EBCDIC, and | |
1507 | |the UTF- encodings, and a string encoded in UTF-EBCDIC may occupy a different | |
1508 | |number of bytes than in UTF-8. | |
