Standard C Library (libc, -lc)


#include <wctype.h> int iswalnum_l(wint_t wc, locale_t loc); int iswalpha_l(wint_t wc, locale_t loc); int iswcntrl_l(wint_t wc, locale_t loc); int iswctype_l(wint_t wc, wctype_t charclass, locale_t loc); int iswdigit_l(wint_t wc, locale_t loc); int iswgraph_l(wint_t wc, locale_t loc); int iswlower_l(wint_t wc, locale_t loc); int iswprint_l(wint_t wc, locale_t loc); int iswpunct_l(wint_t wc, locale_t loc); int iswspace_l(wint_t wc, locale_t loc); int iswupper_l(wint_t wc, locale_t loc); int iswxdigit_l(wint_t wc, locale_t loc); wint_t towlower_l(wint_t wc, locale_t loc); wint_t towupper_l(wint_t wc, locale_t loc); wctype_t wctype_l(const char *property, locale_t loc); int iswblank_l(wint_t wc, locale_t loc); int iswhexnumber_l(wint_t wc, locale_t loc); int iswideogram_l(wint_t wc, locale_t loc); int iswnumber_l(wint_t wc, locale_t loc); int iswphonogram_l(wint_t wc, locale_t loc); int iswrune_l(wint_t wc, locale_t loc); int iswspecial_l(wint_t wc, locale_t loc); wint_t nextwctype_l(wint_t wc, wctype_t wct, locale_t loc); wint_t towctrans_l(wint_t wc, wctrans_t, locale_t loc); wctrans_t wctrans_l(const char *, locale_t loc);


The above functions are character classification utility functions, for use with wide characters (wchar_t or wint_t) in the locale loc. They behave in the same way as the versions without the _l suffix, but use the specified locale rather than the global or per-thread locale. These functions may be implemented as inline functions in <wctype.h> and as functions in the C library. See the specific manual pages for more information.


These functions return the same things as their non-locale versions. If the locale is invalid, their behaviors are undefined.

These functions conform to IEEE Std 1003.1-2008 (``POSIX.1''), except for iswhexnumber_l(), iswideogram_l(), iswnumber_l(), iswphonogram_l(), iswrune_l(), iswspecial_l() and nextwctype_l() which are FreeBSD extensions. DragonFly 3.7 December 25, 2013 DragonFly 3.7
