SYNOPSIS
#include <stdio.h>
int iprintf(const char *<[format]>, ...);
int fiprintf(FILE *<[fd]>, const char *<[format]> , ...);
int siprintf(char *<[str]>, const char *<[format]>, ...);
int sniprintf(char *<[str]>, size_t <[size]>, const char *<[format]>,
...);
int asiprintf(char **<[strp]>, const char *<[format]>, ...);
char *asniprintf(char *<[str]>, size_t *<[size]>,
const char *<[format]>, ...);
int _iprintf_r(struct _reent *<[ptr]>, const char *<[format]>, ...);
int _fiprintf_r(struct _reent *<[ptr]>, FILE *<[fd]>,
const char *<[format]>, ...);
int _siprintf_r(struct _reent *<[ptr]>, char *<[str]>,
const char *<[format]>, ...);
int _sniprintf_r(struct _reent *<[ptr]>, char *<[str]>, size_t <[size]>,
const char *<[format]>, ...);
int _asiprintf_r(struct _reent *<[ptr]>, char **<[strp]>,
const char *<[format]>, ...);
char *_asniprintf_r(struct _reent *<[ptr]>, char *<[str]>,
size_t *<[size]>, const char *<[format]>, ...);
DESCRIPTION
<<iprintf>>, <<fiprintf>>, <<siprintf>>, <<sniprintf>>,
<<asiprintf>>, and <<asniprintf>> are the same as <<printf>>,
<<fprintf>>, <<sprintf>>, <<snprintf>>, <<asprintf>>, and
<<asnprintf>>, respectively, except that they restrict usage
to non-floating-point format specifiers.
<<_iprintf_r>>, <<_fiprintf_r>>, <<_asiprintf_r>>,
<<_siprintf_r>>, <<_sniprintf_r>>, <<_asniprintf_r>> are
simply reentrant versions of the functions above.
RETURNS
Similar to <<printf>>, <<fprintf>>, <<sprintf>>, <<snprintf>>, <<asprintf>>,
and <<asnprintf>>.
PORTABILITY
<<iprintf>>, <<fiprintf>>, <<siprintf>>, <<sniprintf>>, <<asiprintf>>,
and <<asniprintf>> are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
