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
492also in the ASCII character set. For ASCII platforms, the base function with
493no suffix and the one with the C<_A> suffix are identical. On EBCDIC
494platforms, the C<_A> suffix function will not return true unless the specified
495character also has an ASCII equivalent.
496
497Variant C<isFOO_L1> operates on the full Latin1 character set. For EBCDIC
498platforms, the base function with no suffix and the one with the C<_L1> suffix
499are identical. For ASCII platforms, the C<_L1> suffix imposes the Latin-1
500character set onto the platform. That is, the code points that are ASCII are
501unaffected, since ASCII is a subset of Latin-1. But the non-ASCII code points
502are treated as if they are Latin-1 characters. For example, C<isSPACE_L1()>
503will return true when called with the code point 0xA0, which is the Latin-1
504NO-BREAK SPACE.
505
506Variant C<isFOO_uni> is like the C<isFOO_L1> variant, but accepts any UV code
507point as input. If the code point is larger than 255, Unicode rules are used
508to determine if it is in the character class. For example,
509C<isWORDCHAR(0x100)> returns TRUE, since 0x100 is LATIN CAPITAL LETTER A WITH
510MACRON in Unicode, and is a word character.
511
512Variant C<isFOO_utf8> is like C<isFOO_uni>, but the input is a pointer to a
513(known to be well-formed) UTF-8 encoded string (C<U8*> or C<char*>). The
514classification of just the first character in the string is tested.
515
516Variant C<isFOO_LC> is like the C<isFOO_A> and C<isFOO_L1> variants, but uses
517the C library function that gives the named classification instead of
518hard-coded rules. For example, C<isDIGIT_LC()> returns the result of calling
519C<isdigit()>. This means that the result is based on the current locale, which
520is what C<LC> in the name stands for. FALSE is always returned if the input
521won't fit into an octet.
522
523Variant C<isFOO_LC_uvchr> is like C<isFOO_LC>, but is defined on any UV. It
524returns the same as C<isFOO_LC> for input code points less than 256, and
525returns the hard-coded, not-affected-by-locale, Unicode results for larger ones.
526
527Variant C<isFOO_LC_utf8> is like C<isFOO_LC_uvchr>, but the input is a pointer to a
528(known to be well-formed) UTF-8 encoded string (C<U8*> or C<char*>). The
529classification of just the first character in the string is tested.
