wctype — wide-character classification
#include <wctype.h>
wctype_t wctype( |
const char *name); |
The wctype_t type represents a property which a wide character may or may not have. In other words, it represents a class of wide characters. This type's nature is implementation-dependent, but the special value (wctype_t) 0 denotes an invalid property. Nonzero wctype_t values can be passed to the iswctype(3) function to actually test whether a given wide character has the property.
The wctype() function
returns a property, given by its name. The set of valid names
depends on the LC_CTYPE
category of the current locale, but the following names are
valid in all locales.
realizes the isalnum(3) classification function
realizes the isalpha(3) classification function
realizes the isblank(3) classification function
realizes the iscntrl(3) classification function
realizes the isdigit(3) classification function
realizes the isgraph(3) classification function
realizes the islower(3) classification function
realizes the isprint(3) classification function
realizes the ispunct(3) classification function
realizes the isspace(3) classification function
realizes the isupper(3) classification function
realizes the isxdigit(3) classification function
The wctype() function
returns a property descriptor if the name is valid. Otherwise it
returns (wctype_t)
0.
