VIPRINTF(3) NEWLIB VIPRINTF(3)NAME
4.72 `viprintf', `vfiprintf', `vsiprintf', `vsniprintf', `vasiprintf',
`vasniprintf'--format argument list (integer only)
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'.
SEE ALSOviprintf is part of the library. The full documentation for is main‐
