21 29 .SH DESCRIPTION
22 -.sp
23 30 .LP
24 31 If \fIs\fR is a null pointer, the \fBwcrtomb()\fR function is equivalent to the
25 32 call:
26 -.sp
33 +.IP
34 +\fBwcrtomb\fR(\fIbuf\fR, L'\e0', \fIps\fR);
27 35 .LP
28 -wcrtomb(buf, L'\e0', ps)
29 -.sp
30 -.LP
31 36 where \fIbuf\fR is an internal buffer.
32 -.sp
33 37 .LP
34 38 If \fIs\fR is not a null pointer, the \fBwcrtomb()\fR function determines the
35 39 number of bytes needed to represent the character that corresponds to the
36 40 wide-character given by \fIwc\fR (including any shift sequences), and stores
37 41 the resulting bytes in the array whose first element is pointed to by \fIs\fR.
38 42 At most \fBMB_CUR_MAX\fR bytes are stored. If \fIwc\fR is a null
39 43 wide-character, a null byte is stored, preceded by any shift sequence needed to
40 44 restore the initial shift state. The resulting state described is the initial
41 45 conversion state.
42 -.sp
43 46 .LP
44 47 If \fIps\fR is a null pointer, the \fBwcrtomb()\fR function uses its own
45 48 internal \fBmbstate_t\fR object, which is initialized at program startup to the
46 49 initial conversion state. Otherwise, the \fBmbstate_t\fR object pointed to
47 50 by \fIps\fR is used to completely describe the current conversion state of the
48 -associated character sequence. Solaris will behave as if no function defined in
49 -the Solaris Reference Manual calls \fBwcrtomb()\fR.
50 -.sp
51 +associated character sequence. The system will behave as if no function
52 +defined in the Reference Manual calls \fBwcrtomb()\fR.
51 53 .LP
52 -The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
53 -current locale. See \fBenviron\fR(5).
54 +The behavior of \fBwcrtomb()\fR is affected by the \fBLC_CTYPE\fR category of the
55 +current locale. See \fBenviron\fR(5). The function \fBwcrtomb_l()\fR behaves
56 +identically to \fBwcrtomb()\fR, except instead of operating in the current
57 +locale, it operates in the locale specified by \fIloc\fR.
54 58 .SH RETURN VALUES
55 -.sp
56 59 .LP
57 60 The \fBwcrtomb()\fR function returns the number of bytes stored in the array
58 61 object (including any shift sequences). When \fIwc\fR is not a valid
59 62 wide-character, an encoding error occurs. In this case, the function stores
60 63 the value of the macros \fBEILSEQ\fR in \fBerrno\fR and returns
61 64 \fB(size_t)\(mi1\fR; the conversion state is undefined.
62 65 .SH ERRORS
63 -.sp
64 66 .LP
65 67 The \fBwcrtomb()\fR function may fail if:
66 68 .sp
67 69 .ne 2
68 70 .na
69 71 \fB\fBEINVAL\fR\fR
70 72 .ad
71 73 .RS 10n
72 74 The \fIps\fR argument points to an object that contains an invalid conversion
73 75 state.

85 -.SH USAGE
86 -.sp
87 -.LP
88 -If \fIps\fR is not a null pointer, \fBwcrtomb()\fR uses the \fBmbstate_t\fR
89 -object pointed to by \fIps\fR and the function can be used safely in
90 -multithreaded applications, as long as \fBsetlocale\fR(3C) is not being called
91 -to change the locale. If \fIps\fR is a null pointer, \fBwcrtomb()\fR uses its
92 -internal \fBmbstate_t\fR object and the function is Unsafe in multithreaded
93 -applications.
