22 -.sp
23 30 .LP
24 31 If \fIs\fR is not a null pointer, \fBmbtowc()\fR determines the number of the
25 32 bytes that constitute the character pointed to by \fIs\fR. It then determines
26 33 the wide-character code for the value of type \fBwchar_t\fR that corresponds to
27 34 that character. (The value of the wide-character code corresponding to the null
28 35 byte is 0.) If the character is valid and \fIpwc\fR is not a null pointer,
29 36 \fBmbtowc()\fR stores the wide-character code in the object pointed to by
30 37 \fIpwc\fR.
31 -.sp
32 38 .LP
33 39 A call with \fIs\fR as a null pointer causes this function to return \fB0\fR.
34 40 The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
35 41 current locale. At most \fIn\fR bytes of the array pointed to by \fIs\fR will
36 42 be examined.
43 +.LP
44 +The function \fBmbtowc_l()\fR behaves identically to \fBmbtowc()\fR, except
45 +instead of using the current locale, it uses the locale as specified by
46 +\fIloc\fR.
37 47 .SH RETURN VALUES
38 -.sp
39 48 .LP
40 -If \fIs\fR is a null pointer, \fBmbtowc()\fR returns \fB0\fR. If \fIs\fR is not
41 -a null pointer, \fBmbtowc()\fR returns \fB0\fR (if \fIs\fR points to the null
49 +If \fIs\fR is a null pointer, these functions return \fB0\fR. If \fIs\fR is not
50 +a null pointer, they return \fB0\fR (if \fIs\fR points to the null
42 51 byte), the number of bytes that constitute the converted character (if the next
43 52 \fIn\fR or fewer bytes form a valid character), or \fB\(mi1\fR and may set
44 53 \fBerrno\fR to indicate the error (if they do not form a valid character).
45 -.sp
46 54 .LP
47 55 In no case will the value returned be greater than \fIn\fR or the value of the
48 56 \fBMB_CUR_MAX\fR macro.

65 -The \fBmbtowc()\fR function can be used safely in multithreaded applications,
