140 116 .SH DESCRIPTION
141 -.sp
142 117 .LP
143 118 These functions classify character-coded integer values. Each is a
144 119 predicate returning non-zero for true, \fB0\fR for false. The behavior
145 120 of these macros, except \fBisascii()\fR, is affected by the current
146 121 locale (see \fBsetlocale\fR(3C) and \fBuselocale\fR(3C)). To modify
147 122 the behavior, change the \fBLC_TYPE\fR category in \fBsetlocale()\fR, that is,
148 123 \fBsetlocale(\fR\fBLC_CTYPE\fR, \fInewlocale\fR). In the "C" locale,
149 124 or in a locale where character type information is not defined,
150 125 characters are classified according to the rules of the \fBUS-ASCII\fR
151 126 7-bit coded character set.
152 -.sp
153 127 .LP
154 128 The functions \fBisalnum_l()\fR, \fBisalpha_l()\fR, \fBisblank_l()\fR,
155 129 \fBiscntrl_l\fR, \fBisdigit_l()\fR, \fBislower_l()\fR,
156 130 \fBisprint_l()\fR, \fBispunct_l()\fR, \fBisspace_l()\fR,
157 131 \fBisupper_l()\fR, all behave identically to their counterparts without
158 132 the '\fB_l\fR' prefix, except that instead of acting on the current
159 133 locale, that perform the test on the locale specified in the argument
160 134 \fIloc\fR.
161 -.sp
162 135 .LP
163 136 The \fBisascii()\fR macro is defined on all integer values. The rest are
164 137 defined only where the argument is an \fBint\fR, the value of which is
165 138 representable as an \fBunsigned char\fR, or \fBEOF\fR, which is defined by the
166 139 <\fBstdio.h\fR> header and represents end-of-file.
