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>>.
