ANSI_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>>.
