ANSI_SYNOPSIS
#include <stdio.h>
int iprintf(const char *<[format]> [, <[arg]>, ...]);
int fiprintf(FILE *<[fd]>, const char *<[format]> [, <[arg]>, ...]);
int siprintf(char *<[str]>, const char *<[format]> [, <[arg]>, ...]);
int asiprintf(char **<[strp]>, const char *<[format]> [, <[arg]>, ...]);
int sniprintf(char *<[str]>, size_t <[size]>, const char *<[format]>
[, <[arg]>, ...]);
TRAD_SYNOPSIS
#include <stdio.h>
int iprintf(<[format]> [, <[arg]>, ...])
char *<[format]>;
int fiprintf(<[fd]>, <[format]> [, <[arg]>, ...]);
FILE *<[fd]>;
char *<[format]>;
int asiprintf(<[strp]>, <[format]> [, <[arg]>, ...]);
char **<[strp]>;
char *<[format]>;
int siprintf(<[str]>, <[format]> [, <[arg]>, ...]);
char *<[str]>;

char *<[format]>;
DESCRIPTION
<<iprintf>>, <<fiprintf>>, <<siprintf>>, <<sniprintf>>,
<<asiprintf>>, are the same as <<printf>>, <<fprintf>>,
<<sprintf>>, <<snprintf>>, and <<asprintf>>, respectively,
only that they restrict usage to non-floating-point format
specifiers.
RETURNS
<<siprintf>> and <<asiprintf>> return the number of bytes in the output string,
save that the concluding <<NULL>> is not counted.
<<iprintf>> and <<fiprintf>> return the number of characters transmitted.
If an error occurs, <<iprintf>> and <<fiprintf>> return <<EOF>> and
<<asiprintf>> returns -1. No error returns occur for <<siprintf>>.
PORTABILITY
<<iprintf>>, <<fiprintf>>, <<siprintf>>, <<sniprintf>>, and <<asprintf>>
are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
