printf(3W)                       DG/UX 5.4.2                      printf(3W)


NAME
       printf, fprintf, sprintf - print formatted output

SYNOPSIS
       #include <stdio.h>
       #include <widec.h>
       int printf (const char *format [, arg] ... );
       int fprintf (FILE *stream, const char *format [, arg] ... );
       int sprintf (char *s, const char *format [, arg] ... );

DESCRIPTION (International Functions)
       printf() places output on the standard output stream stdout.
       fprintf() places output on the named output stream.  sprintf() places
       output followed by the NULL character in a character array pointed to
       by s.  Each function returns the number of bytes transmitted (not
       including the NULL character in the case of sprintf), or a negative
       value if an output error was encountered.

       Each of these functions converts, formats and prints its args under
       control of the format.  The format is a character string that
       contains two types of object: plain characters, including ASCII
       characters and characters in supplementary code sets which are simply
       copied to the output stream, and conversion specifications which can
       contain only ASCII characters, each of which results in the fetching
       of zero or more args.

       wc and ws are the new conversion specifications for wchart character
       control.  Both wc and ws may be used in all three functions.

       wc     The wchart character arg is transformed into EUC, and then
              printed.  If a field width is specified and the transformed
              EUC has fewer bytes than the field width, it will by padded to
              the given width.  A precision specification is ignored, if
              specified.

       ws     The arg is taken to be a wchart string and the wchart
              characters from the string are transformed into EUC, and
              printed until a wchart null character is encountered or the
              number of bytes indicated by the precision specification is
              printed.  If the precision specification is missing, it is
              taken to be infinite, and all wchart characters up to the
              first wchart null character are transformed into EUC and
              printed.  If a field width is specified and the transformed
              EUC have fewer bytes than the field width, they are padded to
              the given width.

       The ASCII space character (0x20) is used as a padding characters.

DIAGNOSTICS
       printf, fprintf, and sprintf returns the number of bytes transmitted,
       or return a negative value if an error was encountered.
