The \fIcharclass\fR is a string identifying a generic character class for which codeset-specific type information is required. The following character class names are defined in all locales: .sp .sp .TS tab(); lw(1.83i) lw(1.83i) lw(1.83i) lw(1.83i) lw(1.83i) lw(1.83i) . alnumalphablank cntrldigitgraph lowerprintpunct spaceupperxdigit .TE .sp .LP Additional character class names defined in the locale definition file (category \fBLC_CTYPE\fR) can also be specified. .sp .LP The function returns a value of type \fBwctype_t\fR, which can be used as the second argument to subsequent calls of \fBiswctype\fR(3C). \fBwctype()\fR determines values of \fBwctype_t\fR according to the rules of the coded character set defined by character type information in the program's locale (category \fBLC_CTYPE\fR). The values returned by \fBwctype()\fR are valid until a call to \fBsetlocale\fR(3C) that modifies the category \fBLC_CTYPE\fR. .SH RETURN VALUES .sp .LP The \fBwctype()\fR function returns \fB0\fR if the given character class name is not valid for the current locale (category \fBLC_CTYPE\fR); otherwise it returns an object of type \fBwctype_t\fR that can be used in calls to \fBiswctype()\fR. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS tab() box; lw(2.75i) |lw(2.75i) lw(2.75i) |lw(2.75i) . \fBATTRIBUTE TYPE\fR\fBATTRIBUTE VALUE\fR _ CSIEnabled _ Interface StabilityStandard _ MT-LevelMT-Safe with exceptions .TE .SH SEE ALSO .sp .LP \fBiswctype\fR(3C), \fBsetlocale\fR(3C), \fBattributes\fR(5), \fBstandards\fR(5)
