234 .SH DESCRIPTION
235 .sp
236 .LP
237 These functions test whether \fIwc\fR is a wide-character code representing a
238 character of a particular class defined in the \fBLC_CTYPE\fR category of the
239 current locale as determined by \fBsetlocale\fR(3C) and
240 \fBuselocale\fR(3C).
241 .sp
242 .LP
243 The functions \fBiswalpha_l()\fR, \fBiswideogram_l()\fR, \fBiswnumber_l()\fR,
244 \fBiswphonogram_l()\fR, \fBiswspecial_l()\fR, \fBiswalnum_l()\fR,
245 \fBiswascii_l()\fR, \fBiswblank_l()\fR, \fBiswcntrl_l()\fR, \fBiswdigit_l()\fR,
246 \fBiswgraph_l()\fR, \fBiswlower_l()\fR, \fBiswprint_l()\fR, \fBiswpunct_l()\fR,
247 \fBiswspace_l()\fR, \fBiswupper_l()\fR, all behave identically to their
248 counterparts without the '\fB_l\fR' suffix, but instead of operating on the
249 current locale, they operate on the locale specified by \fIloc\fR.
250 .sp
251 .LP
252 The functions, \fBiswideogram()\fR, \fBiswnumber()\fR, \fBiswphonogram()\fR,
253 \fBiswspecial()\fR, and \fBiswhexnumber()\fR, are respectively identical to
254 \fBisideogram()\fR, \fBisnumber()\fR, \fBisphonogram()\fR, \fBisspecial()\fR,
255 \fBiswxdigit()\fR respectively. They are provided for compatability purposes.
256 .sp
257 .LP
258 In all cases, \fIwc\fR is a \fBwint_t\fR, the value of which must be a
259 wide-character code corresponding to a valid character in the current locale or
260 must equal the value of the macro \fBWEOF\fR. If the argument has any other
261 values, the behavior is undefined.

193 .SH DESCRIPTION
194 .LP
195 These functions test whether \fIwc\fR is a wide-character code representing a
196 character of a particular class defined in the \fBLC_CTYPE\fR category of the
197 current locale or the locale specified by \fIloc\fR.
198 .LP
199 The functions \fBiswalpha_l()\fR, \fBiswideogram_l()\fR, \fBiswnumber_l()\fR,
200 \fBiswphonogram_l()\fR, \fBiswspecial_l()\fR, \fBiswalnum_l()\fR,
201 \fBiswascii_l()\fR, \fBiswblank_l()\fR, \fBiswcntrl_l()\fR, \fBiswdigit_l()\fR,
202 \fBiswgraph_l()\fR, \fBiswlower_l()\fR, \fBiswprint_l()\fR, \fBiswpunct_l()\fR,
203 \fBiswspace_l()\fR, \fBiswupper_l()\fR, all behave identically to their
204 counterparts without the '\fB_l\fR' suffix, but instead of operating on the
205 current locale, they operate on the locale specified by \fIloc\fR.
206 .LP
207 The functions, \fBiswideogram()\fR, \fBiswnumber()\fR, \fBiswphonogram()\fR,
208 \fBiswspecial()\fR, and \fBiswhexnumber()\fR, are respectively identical to
209 \fBisideogram()\fR, \fBisnumber()\fR, \fBisphonogram()\fR, \fBisspecial()\fR,
210 \fBiswxdigit()\fR respectively. They are provided for compatability purposes.
211 .LP
212 In all cases, \fIwc\fR is a \fBwint_t\fR, the value of which must be a
213 wide-character code corresponding to a valid character in the current locale or
214 must equal the value of the macro \fBWEOF\fR. If the argument has any other
215 values, the behavior is undefined.
