+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>>.
