   2 FUNCTION
   3         <<iprintf>>---write formatted output (integer only)
   4 INDEX
   5         iprintf
   6
   7 ANSI_SYNOPSIS
   8         #include <stdio.h>
   9
  10         int iprintf(const char *<[format]>, ...);
  11
  12 TRAD_SYNOPSIS
  13         #include <stdio.h>
  14
  15         int iprintf(<[format]> [, <[arg]>, ...])
  16         char *<[format]>;
  17
  18 DESCRIPTION
  19 <<iprintf>> is a restricted version of <<printf>>: it has the same
  20 arguments and behavior, save that it cannot perform any floating-point
  21 formatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers
  22 are not recognized.
  23
  24 RETURNS
  25         <<iprintf>> returns the number of bytes in the output string,
  26         save that the concluding <<NULL>> is not counted.
  27         <<iprintf>> returns when the end of the format string is
  28         encountered.  If an error occurs, <<iprintf>>
  29         returns <<EOF>>.
  30
  31 PORTABILITY
  32 <<iprintf>> is not required by ANSI C.
  33
  34 Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
  35 <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
