137/* XXX A note on the perl source internal type system. The
138 original intent was that I32 be *exactly* 32 bits.
139
140 Currently, we only guarantee that I32 is *at least* 32 bits.
141 Specifically, if int is 64 bits, then so is I32. (This is the case
142 for the Cray.) This has the advantage of meshing nicely with
143 standard library calls (where we pass an I32 and the library is
144 expecting an int), but the disadvantage that an I32 is not 32 bits.

147 There is no guarantee that there is *any* integral type with
148 exactly 32 bits. It is perfectly legal for a system to have
149 sizeof(short) == sizeof(int) == sizeof(long) == 8.

151 Similarly, there is no guarantee that I16 and U16 have exactly 16
152 bits.

476=head1 Character classes
243effed
KW
477This section is about functions (really macros) that classify characters
478into types, such as punctuation versus alphabetic, etc. Most of these are
479analogous to regular expression character classes. (See
480L<perlrecharclass/POSIX Character Classes>.) There are several variants for
481each class. (Not all macros have all variants; each item below lists the
482ones valid for it.) None are affected by C<use bytes>, and only the ones
483with C<LC> in the name are affected by the current locale.
484
485The base function, e.g., C<isALPHA()>, takes an octet (either a C<char> or a
486C<U8>) as input and returns a boolean as to whether or not the character
487represented by that octet is in the named class based on platform, Unicode, and
488Perl rules. If the input is a number that doesn't fit in an octet, FALSE is
489always returned.
490
491Variant C<isFOO_A> (e.g., C<isALPHA_A()>) will return TRUE only if the input is
4b9734bf
KW
492also in the ASCII character set. The base function with no suffix and the one
493with the C<_A> suffix are identical.
494
495Variant C<isFOO_L1> imposes the Latin-1 (or EBCDIC equivlalent) character set
496onto the platform. That is, the code points that are ASCII are unaffected,
497since ASCII is a subset of Latin-1. But the non-ASCII code points are treated
498as if they are Latin-1 characters. For example, C<isWORDCHAR_L1()> will return
499true when called with the code point 0xDF, which is a word character in both
500ASCII and EBCDIC (though it represent different characters in each).
243effed
KW
501
502Variant C<isFOO_uni> is like the C<isFOO_L1> variant, but accepts any UV code
503point as input. If the code point is larger than 255, Unicode rules are used
504to determine if it is in the character class. For example,
505C<isWORDCHAR(0x100)> returns TRUE, since 0x100 is LATIN CAPITAL LETTER A WITH
506MACRON in Unicode, and is a word character.
507
508Variant C<isFOO_utf8> is like C<isFOO_uni>, but the input is a pointer to a
509(known to be well-formed) UTF-8 encoded string (C<U8*> or C<char*>). The
510classification of just the first character in the string is tested.
511
512Variant C<isFOO_LC> is like the C<isFOO_A> and C<isFOO_L1> variants, but uses
513the C library function that gives the named classification instead of
514hard-coded rules. For example, C<isDIGIT_LC()> returns the result of calling
515C<isdigit()>. This means that the result is based on the current locale, which
516is what C<LC> in the name stands for. FALSE is always returned if the input
517won't fit into an octet.
518
519Variant C<isFOO_LC_uvchr> is like C<isFOO_LC>, but is defined on any UV. It
520returns the same as C<isFOO_LC> for input code points less than 256, and
521returns the hard-coded, not-affected-by-locale, Unicode results for larger ones.
522
523Variant C<isFOO_LC_utf8> is like C<isFOO_LC_uvchr>, but the input is a pointer to a
524(known to be well-formed) UTF-8 encoded string (C<U8*> or C<char*>). The
525classification of just the first character in the string is tested.
