-.SH DESCRIPTION
-The
-.BR wcsnrtombs ()
-function is like the
-.BR wcsrtombs (3)
-function,
-except that the number of wide characters to be converted,
-starting at
-.IR *src ,
-is limited to
-.IR nwc .
-.P
-If
-.I dest
-is not NULL,
-the
-.BR wcsnrtombs ()
-function converts
-at most
-.I nwc
-wide characters from
-the wide-character string
-.I *src
-to a multibyte string starting at
-.IR dest .
-At most
-.I len
-bytes are written to
-.IR dest .
-The shift state
-.I *ps
-is updated.
-The conversion is effectively performed by repeatedly
-calling
-.IR "wcrtomb(dest, *src, ps)" ,
-as long as this call succeeds,
-and then incrementing
-.I dest
-by the
-number of bytes written and
-.I *src
-by one.
-The conversion can stop for three reasons:
-.IP \[bu] 3
-A wide character has been encountered that can not be represented as a
-multibyte sequence (according to the current locale).
-In this case,
-.I *src
-is left pointing to the invalid wide character,
-.I (size_t)\ \-1
-is returned,
-and
-.I errno
-is set to
-.BR EILSEQ .
-.IP \[bu]
-.I nwc
-wide characters have been
-converted without encountering a null wide character (L\[aq]\e0\[aq]),
-or the length limit forces a stop.
-In this case,
-.I *src
-is left pointing
-to the next wide character to be converted, and the number of bytes written
-to
-.I dest
-is returned.
-.IP \[bu]
-The wide-character string has been completely converted, including the
-terminating null wide character (which has the side effect of bringing back
-.I *ps
-to the initial state).
-In this case,
-.I *src
-is set to NULL, and the number
-of bytes written to
-.IR dest ,
-excluding the terminating null byte (\[aq]\e0\[aq]), is
-returned.
-.P
-If
-.I dest
-is NULL,
-.I len
-is ignored,
-and the conversion proceeds as above,
-except that the converted bytes are not written out to memory, and that
-no destination length limit exists.
-.P
-In both of the above cases,
-if
-.I ps
-is NULL, a static anonymous
-state known only to the
-.BR wcsnrtombs ()
-function is used instead.
-.P
-The programmer must ensure that there is room for at least
-.I len
-bytes
-at
-.IR dest .
-.SH RETURN VALUE
-The
-.BR wcsnrtombs ()
-function returns
-the number of bytes that make up the
-converted part of multibyte sequence,
-not including the terminating null byte.
-If a wide character was encountered which
-could not be converted,
-.I (size_t)\ \-1
-is returned, and
-.I errno
-set to
-.BR EILSEQ .

-.SH NOTES
-The behavior of

-depends on the

-.P
-Passing NULL as
-.I ps
-is not multithread safe.
