NAME

       fmt_plusminus - write '+' or '-'

SYNTAX

       #include <fmt.h>

       size_t fmt_plusminus(char *dest,signed int source);

DESCRIPTION

       fmt_plusminus writes '-' to dest if source is negative, '+' if source is positive, nothing otherwise.  It returns the number of bytes writ-
       ten.

       fmt_plusminus does not append .

       If dest equals FMT_LEN (i.e. is zero), fmt_plusminus returns the number of bytes it would have written.

NAME

       wcsnrtombs - convert a wide character string to a multibyte string

SYNOPSIS

       #include <wchar.h>

       size_t wcsnrtombs(char *dest, const wchar_t **src, size_t nwc,
			  size_t len, mbstate_t *ps);

DESCRIPTION

       The  wcsnrtombs	function  is  like the wcsrtombs function, except that the number of wide characters to be converted, starting at *src, is
       limited to nwc.

       If dest is not a NULL pointer, the wcsnrtombs function converts at most nwc wide characters from the wide-character string *src to a multi-
       byte  string  starting  at  dest. At most len bytes are written to dest. The shift state *ps is updated. The conversion is effectively per-
       formed by repeatedly calling wcrtomb(dest,*src,ps), as long as this call succeeds, and then incrementing dest by the number of bytes  writ-
       ten and *src by one. The conversion can stop for three reasons:

       1.  A  wide  character  has been encountered that can not be represented as a multibyte sequence (according to the current locale). In this
       case *src is left pointing to the invalid wide character, (size_t)(-1) is returned, and errno is set to EILSEQ.

       2. nwc wide characters have been converted without encountering a L'', or the length limit forces a stop.  In	this  case  *src  is  left
       pointing to the next wide character to be converted, and the number of bytes written to dest is returned.

       3. The wide-character string has been completely converted, including the terminating L'' (which has the side effect of bringing back *ps
       to the initial state). In this case *src is set to NULL, and the number of bytes written to dest, excluding the terminating ''  byte,	is
       returned.

       If  dest  is NULL, 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.

       In both of the above cases, if ps is a NULL pointer, a static anonymous state only known to the wcsnrtombs function is used instead.

       The programmer must ensure that there is room for at least len bytes at dest.

RETURN VALUE

       The 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, (size_t)(-1) is returned, and errno set to EILSEQ.

CONFORMING TO

       This function is a GNU extension.

NOTES

       The behaviour of wcsnrtombs depends on the LC_CTYPE category of the current locale.

       Passing NULL as ps is not multi-thread safe.
