|
||||
character. Although the original @w{ISO C89} standard already defined
|
||||
the type @code{wchar_t} but no functions operating on them were defined.
|
||||
|
||||
The general design of the classification functions for wide characters
|
||||
is more general. It allows to extend the set of available
|
||||
classification beyond the set which is always available. The POSIX
|
||||
standard specifies a way how the extension can be done and this is
|
||||
already implemented in the GNU C library implementation of the
|
||||
@code{localedef} program.
|
||||
|
||||
The character class functions are normally implemented using bitsets.
|
||||
I.e., for the character in question the appropriate bitset is read from
|
||||
a table and a test is performed whether a certain bit is set in this
|
||||
bitset. Which bit is tested for is determined by the class.
|
||||
|
||||
For the wide character classification functions this is made visible.
|
||||
There is a type representing the classification, a function to retrieve
|
||||
this value for a specific class, and a function to test using the
|
||||
classification value whether a given character is in this class. On top
|
||||
of this the normal character classification functions as used for
|
||||
@code{char} objects can be defined.

The @code{wctype} returns a value representing a class of wide

characters which is identified by the string @var{property}. Beside
|

some standard properties each locale can define its own ones. In case

no property with the given name is known for the current locale for the

@section Notes on using the wide character classes
|
||||
|
||||
The first note is probably nothing astonishing but still occasionally a
|
||||
cause of problems. The @code{isw@var{XXX}} functions can be implemented
|
||||
using macros and in fact, the GNU C library does this. They are still
|
||||
available as real functions but when the @file{wctype.h} header is
|
||||
included the macros will be used. This is nothing new compared to the
|
||||
@code{char} type versions of these functions.
|
||||
|
||||
The second notes covers something which is new. It can be best
|
||||
illustrated by a (real-world) example. The first piece of code is an
|
||||
excerpt from the original code. It is truncated a bit but the intention
|
||||
should be clear.
|
||||
|
||||
@smallexample
|
||||
int
|
||||
is_in_class (int c, const char *class)
|
||||
@{
|
||||
if (strcmp (class, "alnum") == 0)
|
||||
return isalnum (c);
|
||||
if (strcmp (class, "alpha") == 0)
|
||||
return isalpha (c);
|
||||
if (strcmp (class, "cntrl") == 0)
|
||||
return iscntrl (c);
|
||||
...
|
||||
return 0;
|
||||
@}
|
||||
@end smallexample
|
||||
|
||||
Now with the @code{wctype} and @code{iswctype} one could avoid the
|
||||
@code{if} cascades. But rewriting the code as follows is wrong:
|
||||
|
||||
@smallexample
|
||||
int
|
||||
is_in_class (int c, const char *class)
|
||||
@{
|
||||
wctype_t desc = wctype (class);
|
||||
return desc ? iswctype ((wint_t) c, desc) : 0;
|
||||
@}
|
||||
@end smallexample
|
||||
|
||||
The problem is that it is not guarateed that the wide character
|
||||
representation of a single-byte character can be found using casting.
|
||||
In fact, usually this fails miserably. The correct solution for this
|
||||
problem is to write the code as follows:
|
||||
|
||||
@smallexample
|
||||
int
|
||||
is_in_class (int c, const char *class)
|
||||
@{
|
||||
wctype_t desc = wctype (class);
|
||||
return desc ? iswctype (btowc (c), desc) : 0;
|
||||
@}
|
||||
@end smallexample
|
||||
|
||||
See @xref{Converting a Character} for more information on @code{btowc}.
|
||||
Please note that this change probably does not improve the performance
|
||||
of the program a lot since the @code{wctype} function still has to make
|
||||
the string comparisons. But it gets really interesting if the
|
||||
@code{is_in_class} function would be called more than once using the
|
||||
same class name. In this case the variable @var{desc} could be computed
|
||||
once and reused for all the calls. Therefore the above form of the
|
||||
function is probably not the final one.
