10 .TH MBSRTOWCS 3C "Nov 1, 2003"
11 .SH NAME
12 mbsrtowcs \- convert a character string to a wide-character string
13 (restartable)
14 .SH SYNOPSIS
15 .LP
16 .nf
17 #include <wchar.h>
18
19 \fBsize_t\fR \fBmbsrtowcs\fR(\fBwchar_t *restrict\fR \fIdst\fR, \fBconst char **restrict\fR \fIsrc\fR,
20 \fBsize_t\fR \fIlen\fR, \fBmbstate_t *restrict\fR \fIps\fR);
21 .fi
22
23 .SH DESCRIPTION
24 .sp
25 .LP
26 The \fBmbsrtowcs()\fR function converts a sequence of characters, beginning in
27 the conversion state described by the object pointed to by \fIps\fR, from the
28 array indirectly pointed to by \fIsrc\fR into a sequence of corresponding
29 wide-characters. If \fIdst\fR is not a null pointer, the converted characters
30 are stored into the array pointed to by \fIdst\fR. Conversion continues up to
31 and including a terminating null character, which is also stored. Conversion
32 stops early in either of the following cases:
33 .RS +4
34 .TP
35 .ie t \(bu
36 .el o
37 When a sequence of bytes is encountered that does not form a valid character.
38 .RE
39 .RS +4
40 .TP
41 .ie t \(bu
42 .el o
43 When \fIlen\fR codes have been stored into the array pointed to by \fIdst\fR
44 (and \fIdst\fR is not a null pointer).
45 .RE
46 .sp
47 .LP
48 Each conversion takes place as if by a call to the \fBmbrtowc()\fR function.
49 .sp
50 .LP
51 If \fIdst\fR is not a null pointer, the pointer object pointed to by \fIsrc\fR
52 is assigned either a null pointer (if conversion stopped due to reaching a
53 terminating null character) or the address just past the last character
54 converted (if any). If conversion stopped due to reaching a terminating null
55 character, and if \fIdst\fR is not a null pointer, the resulting state
56 described is the initial conversion state.
57 .sp
58 .LP
59 If \fIps\fR is a null pointer, the \fBmbsrtowcs()\fR function uses its own
60 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
62 \fIps\fR is used to completely describe the current conversion state of the
63 associated character sequence. Solaris will behave as if no function defined in
64 the Solaris Reference Manual calls \fBmbsrtowcs()\fR.
65 .sp
66 .LP
67 The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
68 current locale. See \fBenviron\fR(5).
69 .SH RETURN VALUES
70 .sp
71 .LP
72 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
76 the number of characters successfully converted, not including the terminating
77 null (if any).
78 .SH ERRORS
79 .sp
80 .LP
81 The \fBmbsrtowcs()\fR function may fail if:
82 .sp
83 .ne 2
84 .na
85 \fB\fBEINVAL\fR\fR
86 .ad
87 .RS 10n
88 The \fIps\fR argument points to an object that contains an invalid conversion
89 state.

126 .LP
127 If \fIps\fR is not a null pointer, \fBmbsrtowcs()\fR uses the \fBmbstate_t\fR
128 object pointed to by \fIps\fR and the function can be used safely in
129 multithreaded applications, as long as \fBsetlocale\fR(3C) is not being called
130 to change the locale. If \fIps\fR is a null pointer, \fBmbsrtowcs()\fR uses its
131 internal \fBmbstate_t\fR object and the function is Unsafe in multithreaded
132 applications.

43 These function converts a sequence of characters, beginning in
44 the conversion state described by the object pointed to by \fIps\fR, from the
45 array indirectly pointed to by \fIsrc\fR into a sequence of corresponding
46 wide-characters. If \fIdst\fR is not a null pointer, the converted characters
47 are stored into the array pointed to by \fIdst\fR. Conversion continues up to

49 stops early in either of the following cases:

62 .RE
63 .LP
64 Each conversion takes place as if by a call to the \fBmbrtowc()\fR function.
65 .LP
66 If \fIdst\fR is not a null pointer, the pointer object pointed to by \fIsrc\fR
67 is assigned either a null pointer (if conversion stopped due to reaching a
68 terminating null character) or the address just past the last character
69 converted (if any). If conversion stopped due to reaching a terminating null
70 character, and if \fIdst\fR is not a null pointer, the resulting state
71 described is the initial conversion state.
72 .LP
73 If \fIps\fR is a null pointer, these functions uses their own
74 internal \fBmbstate_t\fR object, which is initialized at program startup to the
75 initial conversion state. Otherwise, the \fBmbstate_t\fR object pointed to by
76 \fIps\fR is used to completely describe the current conversion state of the
77 associated character sequence. The system will behave as if no function defined
78 in the Reference Manual calls any of these functions.
79 .LP
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.
83 .LP
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.
