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>>.
