51 58 .LP
52 59 The \fBmbrlen()\fR and \fBmbrlen_l()\fR functions return the first of the
53 60 following that applies:

56 63 .na
57 64 \fB\fB0\fR\fR
58 65 .ad
59 66 .RS 17n
60 67 If the next \fIn\fR or fewer bytes complete the character that corresponds to
61 68 the null wide-character.

68 75 .ad
69 76 .RS 17n
70 77 If the next \fIn\fR or fewer bytes complete a valid character; the value
71 78 returned is the number of bytes that complete the character.

79 86 .RS 17n
80 87 If the next \fIn\fR bytes contribute to an incomplete but potentially valid
81 88 character, and all \fIn\fR bytes have been processed. When \fIn\fR has at least
82 89 the value of the \fBMB_CUR_MAX\fR macro, this case can only occur if \fIs\fR
83 90 points at a sequence of redundant shift sequences (for implementations with
84 91 state-dependent encodings).

147 155 If \fIps\fR is not a null pointer, \fBmbrlen()\fR uses the \fBmbstate_t\fR
148 156 object pointed to by \fIps\fR and the function can be used safely in
149 157 multithreaded applications, as long as \fBsetlocale\fR(3C) is not being called
150 158 to change the locale or a per-thread locale has been installed on the calling
151 159 thread with \fBuselocale\fR(3C). If \fIps\fR is a null pointer, \fBmbrlen()\fR
152 160 uses its internal \fBmbstate_t\fR object and the function is Unsafe in
153 161 multithreaded applications.
