FUNCTION
<<siprintf>>---write formatted output (integer only)

INDEX
	siprintf

ANSI_SYNOPSIS
        #include <stdio.h>

        int siprintf(char *<[str]>, const char *<[format]> [, <[arg]>, ...]);


DESCRIPTION
<<siprintf>> is a restricted version of <<sprintf>>: it has the same
arguments and behavior, save that it cannot perform any floating-point
formatting: the <<f>>, <<g>>, <<G>>, <<e>>, and <<F>> type specifiers
are not recognized.

RETURNS
        <<siprintf>> returns the number of bytes in the output string,
        save that the concluding <<NULL>> is not counted.
        <<siprintf>> returns when the end of the format string is
        encountered.

PORTABILITY
<<siprintf>> is not required by ANSI C.

Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
