.Dd July 21, 2005 .Dt NEXTWCTYPE 3 .Os .Sh NAME .Nm nextwctype , .Nm nextwctype_l .Nd "iterate through character classes" .Sh LIBRARY .Lb libc .Sh SYNOPSIS n wctype.h .Ft wint_t .Fn nextwctype "wint_t ch" "wctype_t wct" n xlocale.h .Ft wint_t .Fn nextwctype_l "wint_t ch" "wctype_t wct" "locale_t loc" .Sh DESCRIPTION The .Fn nextwctype function determines the next character after .Fa ch that is a member of character class .Fa wct . If .Fa ch is -1, the search begins at the first member of .Fa wct .

p While the .Fn nextwctype function uses the current locale, the .Fn nextwctype_l function may be passed a locale directly. See .Xr xlocale 3 for more information. .Sh RETURN VALUES The .Fn nextwctype function returns the next character, or -1 if there are no more. .Sh COMPATIBILITY This function is a non-standard .Fx extension and should not be used where the standard .Fn iswctype function would suffice. .Sh SEE ALSO .Xr wctype 3 , .Xr xlocale 3 .Sh HISTORY The .Fn nextwctype function appeared in .Fx 5.4 .
