/* XXX A note on the perl source internal type system. The
original intent was that I32 be *exactly* 32 bits.
Currently, we only guarantee that I32 is *at least* 32 bits.
Specifically, if int is 64 bits, then so is I32. (This is the case
for the Cray.) This has the advantage of meshing nicely with
standard library calls (where we pass an I32 and the library is
expecting an int), but the disadvantage that an I32 is not 32 bits.
Andy Dougherty August 1996
There is no guarantee that there is *any* integral type with
exactly 32 bits. It is perfectly legal for a system to have
sizeof(short) == sizeof(int) == sizeof(long) == 8.
Similarly, there is no guarantee that I16 and U16 have exactly 16
bits.
For dealing with issues that may arise from various 32/64-bit
systems, we will ask Configure to check out
SHORTSIZE == sizeof(short)
INTSIZE == sizeof(int)
LONGSIZE == sizeof(long)
LONGLONGSIZE == sizeof(long long) (if HAS_LONG_LONG)
PTRSIZE == sizeof(void *)
DOUBLESIZE == sizeof(double)
LONG_DOUBLESIZE == sizeof(long double) (if HAS_LONG_DOUBLE).

=head1 Character classes
There are three variants for all the functions in this section. The base ones
operate using the character set of the platform Perl is running on. The ones
with an C<_A> suffix operate on the ASCII character set, and the ones with an
C<_L1> suffix operate on the full Latin1 character set. All are unaffected by
locale
For ASCII platforms, the base function with no suffix and the one with the
C<_A> suffix are identical. The function with the C<_L1> suffix imposes the
Latin-1 character set onto the platform. That is, the code points that are
ASCII are unaffected, since ASCII is a subset of Latin-1. But the non-ASCII
code points are treated as if they are Latin-1 characters. For example,
C<isSPACE_L1()> will return true when called with the code point 0xA0, which is
the Latin-1 NO-BREAK SPACE.
For EBCDIC platforms, the base function with no suffix and the one with the
C<_L1> suffix should be identical, since, as of this writing, the EBCDIC code
pages that Perl knows about all are equivalent to Latin-1. The function that
ends in an C<_A> suffix will not return true unless the specified character also
has an ASCII equivalent.
=for apidoc Am|bool|isALPHA|char ch
Returns a boolean indicating whether the specified character is an
alphabetic character in the platform's native character set.
See the L<top of this section|/Character classes> for an explanation of variants
C<isALPHA_A> and C<isALPHA_L1>.
=for apidoc Am|bool|isASCII|char ch
Returns a boolean indicating whether the specified character is one of the 128
characters in the ASCII character set. On non-ASCII platforms, it is if this
character corresponds to an ASCII character. Variants C<isASCII_A()> and
C<isASCII_L1()> are identical to C<isASCII()>.
=for apidoc Am|bool|isDIGIT|char ch
Returns a boolean indicating whether the specified character is a
digit in the platform's native character set.
Variants C<isDIGIT_A> and C<isDIGIT_L1> are identical to C<isDIGIT>.
=for apidoc Am|bool|isLOWER|char ch
Returns a boolean indicating whether the specified character is a
lowercase character in the platform's native character set.
See the L<top of this section|/Character classes> for an explanation of variants
C<isLOWER_A> and C<isLOWER_L1>.
=for apidoc Am|bool|isOCTAL|char ch
Returns a boolean indicating whether the specified character is an
octal digit, [0-7] in the platform's native character set.
Variants C<isOCTAL_A> and C<isOCTAL_L1> are identical to C<isOCTAL>.
=for apidoc Am|bool|isSPACE|char ch
Returns a boolean indicating whether the specified character is a
whitespace character in the platform's native character set. This is the same
as what C<\s> matches in a regular expression.
See the L<top of this section|/Character classes> for an explanation of variants
C<isSPACE_A> and C<isSPACE_L1>.
=for apidoc Am|bool|isUPPER|char ch
Returns a boolean indicating whether the specified character is an
uppercase character in the platform's native character set.
See the L<top of this section|/Character classes> for an explanation of variants
C<isUPPER_A> and C<isUPPER_L1>.
=for apidoc Am|bool|isWORDCHAR|char ch
Returns a boolean indicating whether the specified character is a
character that is any of: alphabetic, numeric, or an underscore. This is the
same as what C<\w> matches in a regular expression.
C<isALNUM()> is a synonym provided for backward compatibility. Note that it
does not have the standard C language meaning of alphanumeric, since it matches
an underscore and the standard meaning does not.
See the L<top of this section|/Character classes> for an explanation of variants
C<isWORDCHAR_A> and C<isWORDCHAR_L1>.
=for apidoc Am|bool|isXDIGIT|char ch
Returns a boolean indicating whether the specified character is a hexadecimal
digit, [0-9A-Fa-f]. Variants C<isXDIGIT_A()> and C<isXDIGIT_L1()> are
identical to C<isXDIGIT()>.
=head1 Character case changing
=for apidoc Am|char|toUPPER|char ch
Converts the specified character to uppercase in the platform's native
character set, if possible; otherwise returns the input character itself.
=for apidoc Am|char|toLOWER|char ch
Converts the specified character to lowercase in the platform's native
character set, if possible; otherwise returns the input character itself.

=head1 Memory Management
=for apidoc Am|void|Newx|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<malloc> function.
In 5.9.3, Newx() and friends replace the older New() API, and drops
the first parameter, I<x>, a debug aid which allowed callers to identify
themselves. This aid has been superseded by a new build option,
PERL_MEM_LOG (see L<perlhack/PERL_MEM_LOG>). The older API is still
there for use in XS modules supporting older perls.
=for apidoc Am|void|Newxc|void* ptr|int nitems|type|cast
The XSUB-writer's interface to the C C<malloc> function, with
cast. See also C<Newx>.
=for apidoc Am|void|Newxz|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<malloc> function. The allocated
memory is zeroed with C<memzero>. See also C<Newx>.
=for apidoc Am|void|Renew|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<realloc> function.
=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
The XSUB-writer's interface to the C C<realloc> function, with
cast.
=for apidoc Am|void|Safefree|void* ptr
The XSUB-writer's interface to the C C<free> function.
=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
The XSUB-writer's interface to the C C<memmove> function. The C<src> is the
source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
the type. Can do overlapping moves. See also C<Copy>.
=for apidoc Am|void *|MoveD|void* src|void* dest|int nitems|type
Like C<Move> but returns dest. Useful for encouraging compilers to tail-call
optimise.
=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
The XSUB-writer's interface to the C C<memcpy> function. The C<src> is the
source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
the type. May fail on overlapping copies. See also C<Move>.
=for apidoc Am|void *|CopyD|void* src|void* dest|int nitems|type
Like C<Copy> but returns dest. Useful for encouraging compilers to tail-call
optimise.
=for apidoc Am|void|Zero|void* dest|int nitems|type
The XSUB-writer's interface to the C C<memzero> function. The C<dest> is the
destination, C<nitems> is the number of items, and C<type> is the type.
