.SH NAME
wcrtomb, wcrtomb_l \- convert a wide-character code to a character (restartable)
.SH SYNOPSIS
.LP
.nf
#include <stdio.h>
\fBsize_t\fR \fBwcrtomb\fR(\fBchar *restrict\fR \fIs\fR, \fBwchar_t\fR \fIwc\fR, \fBmbstate_t *restrict\fR \fIps\fR);
- \fBsize_t\fR \fBwcrtomb_l\fR(\fBchar *restrict\fR \fIs\fR, \fBwchar_t\fR \fIwc\fR, \fBmbstate_t *restrict\fR \fIps\fR, \fBlocale_t\fR \fIloc\fR);
.fi
.SH DESCRIPTION
- .sp
.LP
If \fIs\fR is a null pointer, the \fBwcrtomb()\fR function is equivalent to the
call:
! .sp
.LP
- wcrtomb(buf, L'\e0', ps)
- .sp
- .LP
where \fIbuf\fR is an internal buffer.
- .sp
.LP
If \fIs\fR is not a null pointer, the \fBwcrtomb()\fR function determines the
number of bytes needed to represent the character that corresponds to the
wide-character given by \fIwc\fR (including any shift sequences), and stores
the resulting bytes in the array whose first element is pointed to by \fIs\fR.
At most \fBMB_CUR_MAX\fR bytes are stored. If \fIwc\fR is a null
wide-character, a null byte is stored, preceded by any shift sequence needed to
restore the initial shift state. The resulting state described is the initial
conversion state.
- .sp
.LP
If \fIps\fR is a null pointer, the \fBwcrtomb()\fR function uses its own
internal \fBmbstate_t\fR object, which is initialized at program startup to the
initial conversion state. Otherwise, the \fBmbstate_t\fR object pointed to
by \fIps\fR is used to completely describe the current conversion state of the
! associated character sequence. illumos will behave as if no function defined in
! the illumos Reference Manual calls \fBwcrtomb()\fR.
! .sp
.LP
! The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
current locale. See \fBenviron\fR(5). The function \fBwcrtomb_l()\fR behaves
! identically to \fBwcrtomb\fR, except instead of operating in the current
! environemtn, it operates in the environment specified by \fIloc\fR.
.SH RETURN VALUES
- .sp
.LP
The \fBwcrtomb()\fR function returns the number of bytes stored in the array
object (including any shift sequences). When \fIwc\fR is not a valid
wide-character, an encoding error occurs. In this case, the function stores
the value of the macros \fBEILSEQ\fR in \fBerrno\fR and returns
\fB(size_t)\(mi1\fR; the conversion state is undefined.
.SH ERRORS
- .sp
.LP
The \fBwcrtomb()\fR function may fail if:

- .LP
- If \fIps\fR is not a null pointer, \fBwcrtomb()\fR uses the \fBmbstate_t\fR

- multithreaded applications, as long as \fBsetlocale\fR(3C) is not being called
