Libraries13.2.29. wctype.hMost functions in wctype.h represent the wide-character variant of functions declared in ctype.h andare discussed in Section 13.2.4, ctype.h and wctype.h. In addition, this header file provides extensible,locale specific functions and wide character classification.wctype(*property) Constructs a value of type wctype_t that describes a class of wide charactersidentified by the string *property. If property identifies a valid class of wide charactersaccording to the LC_TYPE category (see Section 13.2.14, locale.h) of the currentlocale, a non-zero value is returned that can be used as an argument in theiswctype function.iswctype(wc,desc) Tests whether the wide character wc is a member of the class represented bywctype_t desc. Returns a non-zero value if tested true.Functioniswalnum(wc)iswalpha(wc)iswcntrl(wc)iswdigit(wc)iswgraph(wc)iswlower(wc)iswprint(wc)iswpunct(wc)iswspace(wc)iswupper(wc)iswxditig(wc)Equivalent to locale specific testiswctype(wc,wctype("alnum"))iswctype(wc,wctype("alpha"))iswctype(wc,wctype("cntrl"))iswctype(wc,wctype("digit"))iswctype(wc,wctype("graph"))iswctype(wc,wctype("lower"))iswctype(wc,wctype("print"))iswctype(wc,wctype("punct"))iswctype(wc,wctype("space"))iswctype(wc,wctype("upper"))iswctype(wc,wctype("xdigit"))wctrans(*property) Constructs a value of type wctype_t that describes a mapping between widecharacters identified by the string *property. If property identifies a valid mappingof wide characters according to the LC_TYPE category (see Section 13.2.14,locale.h) of the current locale, a non-zero value is returned that can be used as anargument in the towctrans function.towctrans(wc,desc) Transforms wide character wc into another wide-character, described by desc.Functiontowlower(wc)towupper(wc)Equivalent to locale specific transformationtowctrans(wc,wctrans("tolower")towctrans(wc,wctrans("toupper")13.3. C Library ReentrancySome of the functions in the C library are reentrant, others are not. The table below shows the functionsin the C library, and whether they are reentrant or not. A dash means that the function is reentrant. Note773
