+.TH wctomb 3 2023-07-20 "Linux man-pages 6.05.01"
+.SH NAME
+wctomb \- convert a wide character to a multibyte sequence
+.SH LIBRARY
+Standard C library
+.RI ( libc ", " \-lc )
+.SH SYNOPSIS
+.nf
+.B #include <stdlib.h>
+.PP
+.BI "int wctomb(char *" s ", wchar_t " wc );
+.fi
+.SH DESCRIPTION
+If
+.I s
+is not NULL,
+the
+.BR wctomb ()
+function converts the wide character
+.I wc
+to its multibyte representation and stores it at the beginning of
+the character array pointed to by
+.IR s .
+It updates the shift state, which
+is stored in a static anonymous variable
+known only to the
+.BR wctomb ()
+function,
+and returns the length of said multibyte representation,
+that is, the number of
+bytes written at
+.IR s .
+.PP
+The programmer must ensure that there is
+room for at least
+.B MB_CUR_MAX
+bytes at
+.IR s .
+.PP
+If
+.I s
+is NULL, the
+.BR wctomb ()
+function
+.\" The Dinkumware doc and the Single UNIX specification say this, but
+.\" glibc doesn't implement this.
+resets the shift state, known only to this function,
+to the initial state, and
+returns nonzero if the encoding has nontrivial shift state,
+or zero if the encoding is stateless.
+.SH RETURN VALUE
+If
+.I s
+is not NULL, the
+.BR wctomb ()
+function
+returns the number of bytes
+that have been written to the byte array at
+.IR s .
+If
+.I wc
+can not be
+represented as a multibyte sequence (according
+to the current locale), \-1 is returned.
+.PP
+If
+.I s
+is NULL, the
+.BR wctomb ()
+function returns nonzero if the
+encoding has nontrivial shift state, or zero if the encoding is stateless.
+.SH ATTRIBUTES
+For an explanation of the terms used in this section, see

+.SH VERSIONS
+The function

+.SH HISTORY

+.SH NOTES
+The behavior of
