FUNCTION
<<iprintf>>---write formatted output (integer only)
INDEX
iprintf
ANSI_SYNOPSIS
#include <stdio.h>
int iprintf(const char *<[format]>, ...);
TRAD_SYNOPSIS
#include <stdio.h>
int iprintf(<[format]> [, <[arg]>, ...])
char *<[format]>;
DESCRIPTION
<<iprintf>> is a restricted version of <<printf>>: it has the same
arguments and behavior, save that it cannot perform any floating-point
formatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers
are not recognized.
RETURNS
<<iprintf>> returns the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<iprintf>> returns when the end of the format string is
encountered. If an error occurs, <<iprintf>>
returns <<EOF>>.
PORTABILITY
<<iprintf>> is not required by ANSI C.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
