/*FUNCTION        <<iprintf>>---write formatted output (integer only)INDEX	iprintfANSI_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 samearguments and behavior, save that it cannot perform any floating-pointformatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiersare 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>>.*/#include <_ansi.h>#include <stdio.h>#include "local.h"#ifndef _REENT_ONLY#ifdef _HAVE_STDC#include <stdarg.h>intiprintf (const char *fmt,...){  int ret;  va_list ap;  _REENT_SMALL_CHECK_INIT(_stdout_r (_REENT));  va_start (ap, fmt);  _stdout_r (_REENT)->_data = _REENT;  ret = vfiprintf (stdout, fmt, ap);  va_end (ap);  return ret;}#else#include <varargs.h>intiprintf (fmt, va_alist)     char *fmt;     va_dcl{  int ret;  va_list ap;  _REENT_SMALL_CHECK_INIT(_stdout_r (_REENT));  va_start (ap);  _stdout_r (_REENT)->_data = _REENT;  ret = vfiprintf (stdout, fmt, ap);  va_end (ap);  return ret;}#endif /* ! _HAVE_STDC */#endif /* ! _REENT_ONLY */#ifdef _HAVE_STDC#include <stdarg.h>int_iprintf_r (struct _reent *ptr, const char *fmt, ...){  int ret;  va_list ap;  _REENT_SMALL_CHECK_INIT(_stdout_r (ptr));  va_start (ap, fmt);  ret = vfiprintf (_stdout_r (ptr), fmt, ap);  va_end (ap);  return ret;}#else#include <varargs.h>int_iprintf_r (data, fmt, va_alist)     char *data;     char *fmt;     va_dcl{  int ret;  struct _reent *ptr = data;  va_list ap;  _REENT_SMALL_CHECK_INIT(_stdout_r (ptr));  va_start (ap);  ret = vfiprintf (_stdout_r (ptr), fmt, ap);  va_end (ap);  return ret;}#endif
