SYNOPSIS
#include <stdio.h>
#include <stdarg.h>
int viprintf(const char *<[fmt]>, va_list <[list]>);
int vfiprintf(FILE *<[fp]>, const char *<[fmt]>, va_list <[list]>);
int vsiprintf(char *<[str]>, const char *<[fmt]>, va_list <[list]>);
int vsniprintf(char *<[str]>, size_t <[size]>, const char *<[fmt]>,
va_list <[list]>);
int vasiprintf(char **<[strp]>, const char *<[fmt]>, va_list <[list]>);
char *vasniprintf(char *<[str]>, size_t *<[size]>, const char *<[fmt]>,
va_list <[list]>);
int _viprintf_r(struct _reent *<[reent]>, const char *<[fmt]>,
va_list <[list]>);
int _vfiprintf_r(struct _reent *<[reent]>, FILE *<[fp]>,
const char *<[fmt]>, va_list <[list]>);
int _vsiprintf_r(struct _reent *<[reent]>, char *<[str]>,
const char *<[fmt]>, va_list <[list]>);
int _vsniprintf_r(struct _reent *<[reent]>, char *<[str]>,
size_t <[size]>, const char *<[fmt]>, va_list <[list]>);
int _vasiprintf_r(struct _reent *<[reent]>, char **<[str]>,
const char *<[fmt]>, va_list <[list]>);
char *_vasniprintf_r(struct _reent *<[reent]>, char *<[str]>,
size_t *<[size]>, const char *<[fmt]>, va_list <[list]>);
DESCRIPTION
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>>,
<<vsniprintf>>, and <<vasniprintf>> are (respectively) variants of
<<iprintf>>, <<fiprintf>>, <<asiprintf>>, <<siprintf>>, <<sniprintf>>,
and <<asniprintf>>. They differ only in allowing their caller to pass
the variable argument list as a <<va_list>> object (initialized by
<<va_start>>) rather than directly accepting a variable number of
arguments. The caller is responsible for calling <<va_end>>.
<<_viprintf_r>>, <<_vfiprintf_r>>, <<_vasiprintf_r>>,
<<_vsiprintf_r>>, <<_vsniprintf_r>>, and <<_vasniprintf_r>> are
reentrant versions of the above.
RETURNS
The return values are consistent with the corresponding functions:
PORTABILITY
All of these functions are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
