40 41 .SH DESCRIPTION
41 42 .LP
42 43 The \fBwcsrtombs()\fR function converts a sequence of wide-characters from the
43 44 array indirectly pointed to by \fIsrc\fR into a sequence of corresponding
44 45 characters, beginning in the conversion state described by the object pointed
45 46 to by \fIps\fR. If \fIdst\fR is not a null pointer, the converted characters
46 47 are then stored into the array pointed to by \fIdst\fR. Conversion continues up
47 48 to and including a terminating null wide-character, which is also stored.
48 49 Conversion stops earlier in the following cases:
49 50 .RS +4
50 51 .TP
51 52 .ie t \(bu
52 53 .el o
53 54 When a code is reached that does not correspond to a valid character.
54 55 .RE
55 56 .RS +4
56 57 .TP
57 58 .ie t \(bu
58 59 .el o
59 60 When the next character would exceed the limit of \fIlen\fR total bytes to be
60 61 stored in the array pointed to by \fIdst\fR (and \fIdst\fR is not a null
61 62 pointer).
62 63 .RE
63 64 .RS +4
64 65 .TP
65 66 .ie t \(bu
66 67 .el o
67 68 In the case of \fBwcsnrtombs()\fR and \fBwcsnrtombs_l()\fR, when \fInwc\fR
68 69 wide characters have been completely converted.
69 70 .RE
70 71 .LP
71 72 Each conversion takes place as if by a call to the \fBwcrtomb()\fR function.
72 73 .LP
73 74 If \fIdst\fR is not a null pointer, the pointer object pointed to by \fIsrc\fR
74 75 is assigned either a null pointer (if conversion stopped due to reaching a
75 76 terminating null wide-character) or the address just past the last
76 77 wide-character converted (if any). If conversion stopped due to reaching a
77 78 terminating null wide-character, the resulting state described is the initial
78 79 conversion state.
79 80 .LP
80 81 If \fIps\fR is a null pointer, these functions uses their own
81 82 internal \fBmbstate_t\fR object, which is initialized at program startup to the
82 83 initial conversion state. Otherwise, the \fBmbstate_t\fR object pointed to by
83 84 \fIps\fR is used to completely describe the current conversion state of the
84 85 associated character sequence. The system will behave as if no function defined
85 86 in the Reference Manual calls any of these functions.
86 87 .LP
87 88 The behavior of \fBwcsrtombs()\fR and \fBwcsnrtombs()\fR are affected by the
88 89 \fBLC_CTYPE\fR category of the current locale. See \fBenviron\fR(5).
89 90 .LP
90 91 The \fBwcsrtombs_l()\fR and \fBwcsnrtombs_l()\fR functions behave identically
91 92 to \fBwcsrtombs()\fR and \fBwcsnrtombs()\fR respectively, except
92 93 that instead of operating in the current locale, they operate in the locale
93 94 specified by \fIloc\fR.
94 95 .SH RETURN VALUES
95 96 .LP
96 97 If conversion stops because a code is reached that does not correspond to a
97 98 valid character, an encoding error occurs. In this case, these
98 99 functions store the value of the macro \fBEILSEQ\fR in \fBerrno\fR and return
99 100 \fB(size_t)\(mi1\fR; the conversion state is undefined. Otherwise, they return
100 101 the number of bytes in the resulting character sequence, not including the
101 102 terminating null (if any).
102 103 .SH ERRORS
103 104 .LP
104 105 These functions may fail if:
105 106 .sp
106 107 .ne 2
107 108 .na
108 109 \fB\fBEINVAL\fR\fR
109 110 .ad
110 111 .RS 10n
111 112 The \fIps\fR argument points to an object that contains an invalid conversion
112 113 state.
113 114 .RE
114 115
115 116 .sp
116 117 .ne 2
117 118 .na
118 119 \fB\fBEILSEQ\fR\fR
119 120 .ad
120 121 .RS 10n
121 122 A wide-character code does not correspond to a valid character.

141 142 If \fIps\fR is a null pointer, these functions should be considered Unsafe
