43 +These function converts a sequence of characters, beginning in

28 45 array indirectly pointed to by \fIsrc\fR into a sequence of corresponding

48 64 Each conversion takes place as if by a call to the \fBmbrtowc()\fR function.
49 -.sp
50 65 .LP
51 66 If \fIdst\fR is not a null pointer, the pointer object pointed to by \fIsrc\fR
52 67 is assigned either a null pointer (if conversion stopped due to reaching a
53 68 terminating null character) or the address just past the last character
54 69 converted (if any). If conversion stopped due to reaching a terminating null
55 70 character, and if \fIdst\fR is not a null pointer, the resulting state
56 71 described is the initial conversion state.

59 -If \fIps\fR is a null pointer, the \fBmbsrtowcs()\fR function uses its own
73 +If \fIps\fR is a null pointer, these functions uses their own
60 74 internal \fBmbstate_t\fR object, which is initialized at program startup to the
61 -initial conversion state. Otherwise, the \fBmbstate_t\fR object pointed to by
75 +initial conversion state. Otherwise, the \fBmbstate_t\fR object pointed to by
62 76 \fIps\fR is used to completely describe the current conversion state of the

78 +in the Reference Manual calls any of these functions.

67 -The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
68 -current locale. See \fBenviron\fR(5).
80 +The function \fBmbsnrtowcs()\fR behaves identically to \fBmbsrtowcs()\fR,
81 +except the conversion stops after reading \fInms\fR bytes from the
82 +buffer pointed to by \fIsrc\fR.

84 +The behavior of \fBmbnrtowcs()\fR and \fBmbsrtowcs()\fR functions are
85 +affected by the \fBLC_CTYPE\fR category of the
86 +current locale. See \fBenviron\fR(5). The functions \fBmbsrtowcs_l()\fR and
87 +\fBmbsnrtowcs_l()\fR behave identically to \fBmbsrtowcs()\fR and
88 +\fBmbsnrtowcs()\fR, except that instead of using the current locale, they use
89 +the locale specified by \fIloc\fR.
69 90 .SH RETURN VALUES
70 -.sp
71 91 .LP
72 92 If the input conversion encounters a sequence of bytes that do not form a valid
73 -character, an encoding error occurs. In this case, the \fBmbsrtowcs()\fR
74 -function stores the value of the macro \fBEILSEQ\fR in \fBerrno\fR and returns
75 -\fB(size_t)\(mi1\fR; the conversion state is undefined. Otherwise, it returns
93 +character, an encoding error occurs. In this case, these
94 +functions store the value of the macro \fBEILSEQ\fR in \fBerrno\fR and return
95 +\fB(size_t)\(mi1\fR; the conversion state is undefined. Otherwise, they return
76 96 the number of characters successfully converted, not including the terminating
77 97 null (if any).
