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.
693762b4 150

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

472There are three variants for all the functions in this section. The base ones
473operate using the character set of the platform Perl is running on. The ones
474with an C<_A> suffix operate on the ASCII character set, and the ones with an
475C<_L1> suffix operate on the full Latin1 character set. All are unaffected by
d0df0e98 476locale.
8a58bdcf
KW
477
478For ASCII platforms, the base function with no suffix and the one with the
479C<_A> suffix are identical. The function with the C<_L1> suffix imposes the
480Latin-1 character set onto the platform. That is, the code points that are
481ASCII are unaffected, since ASCII is a subset of Latin-1. But the non-ASCII
482code points are treated as if they are Latin-1 characters. For example,
483C<isSPACE_L1()> will return true when called with the code point 0xA0, which is
484the Latin-1 NO-BREAK SPACE.
485
486For EBCDIC platforms, the base function with no suffix and the one with the
487C<_L1> suffix should be identical, since, as of this writing, the EBCDIC code
488pages that Perl knows about all are equivalent to Latin-1. The function that
489ends in an C<_A> suffix will not return true unless the specified character also
490has an ASCII equivalent.
