see -.BR fwide (3) -for more information. -.P -The -.BR fwprintf () -and -.BR vfwprintf () -functions -perform wide-character output to -.IR stream . -.I stream -must not be byte oriented; see -.BR fwide (3) -for more information. -.P -The -.BR swprintf () -and -.BR vswprintf () -functions -perform wide-character output -to an array of wide characters. -The programmer must ensure that there is -room for at least -.I maxlen -wide -characters at -.IR wcs . -.P -These functions are like -the -.BR printf (3), -.BR vprintf (3), -.BR fprintf (3), -.BR vfprintf (3), -.BR sprintf (3), -.BR vsprintf (3) -functions except for the -following differences: -.TP -.B \[bu] -The -.I format -string is a wide-character string. -.TP -.B \[bu] -The output consists of wide characters, not bytes. -.TP -.B \[bu] -.BR swprintf () -and -.BR vswprintf () -take a -.I maxlen -argument, -.BR sprintf (3) -and -.BR vsprintf (3) -do not. -.RB ( snprintf (3) -and -.BR vsnprintf (3) -take a -.I maxlen -argument, but these functions do not return \-1 upon -buffer overflow on Linux.) -.P -The treatment of the conversion characters -.B c -and -.B s -is different: -.TP -.B c -If no -.B l -modifier is present, the -.I int -argument is converted to a wide character by a call to the -.BR btowc (3) -function, and the resulting wide character is written. -If an -.B l -modifier is present, the -.I wint_t -(wide character) argument is written. -.TP -.B s -If no -.B l -modifier is present: the -.I "const\ char\ *" -argument is expected to be a pointer to an array of character type -(pointer to a string) containing a multibyte character sequence beginning -in the initial shift state. -Characters from the array are converted to -wide characters (each by a call to the -.BR mbrtowc (3) -function with a conversion state starting in the initial state before -the first byte). -The resulting wide characters are written up to -(but not including) the terminating null wide character (L\[aq]\e0\[aq]). -If a precision is -specified, no more wide characters than the number specified are written. -Note that the precision determines the number of -.I wide characters -written, not the number of -.I bytes -or -.IR "screen positions" . -The array must contain a terminating null byte (\[aq]\e0\[aq]), -unless a precision is given -and it is so small that the number of converted wide characters reaches it -before the end of the array is reached. -If an -.B l -modifier is present: the -.I "const\ wchar_t\ *" -argument is expected to be a pointer to an array of wide characters. -Wide characters from the array are written up to (but not including) a -terminating null wide character. -If a precision is specified, no more than -the number specified are written. -The array must contain a terminating null -wide character, unless a precision is given and it is smaller than or equal -to the number of wide characters in the array. -.SH RETURN VALUE -The functions return the number of wide characters written, excluding the -terminating null wide character in -case of the functions -.BR swprintf () -and -.BR vswprintf (). -They return \-1 when an error occurs. -.SH ATTRIBUTES -For an explanation of the terms used in this section, see -.BR attributes (7). -.TS -allbox;
