+*
+*Purpose:
+*	defines printf() - print formatted data
+*
+*Revision History:
+*	09-02-83  RN	initial version
+*	04-13-87  JCR	added const to declaration
+*	06-24-87  JCR	(1) Made printf conform to ANSI prototype and use the
+*			va_ macros; (2) removed SS_NE_DS conditionals.
+*	11-04-87  JCR	Multi-thread support
+*	12-11-87  JCR	Added "_LOAD_DS" to declaration
+*	05-27-88  PHG	Merged DLL and normal versions
+*	06-14-88  JCR	Use near pointer to reference _iob[] entries
+*	08-17-89  GJF	Clean up, now specific to OS/2 2.0 (i.e., 386 flat
+*			model). Also fixed copyright and indents.
+*	02-15-90  GJF	Fixed copyright
+*	03-19-90  GJF	Made calling type _CALLTYPE2, added #include
+*			<cruntime.h> and removed #include <register.h>.
+*	07-23-90  SBM	Replaced <assertm.h> by <assert.h>
+*	10-03-90  GJF	New-style function declarator.

+*int printf(format, ...) - print formatted data
+*
+*Purpose:
+*	Prints formatted data on stdout using the format string to
+*	format data and getting as many arguments as called for
+*	Uses temporary buffering to improve efficiency.
+*	_output does the real work here
+*
+*Entry:
+*	char *format - format string to control data format/number of arguments
+*	followed by list of arguments, number and type controlled by
+*	format string
+*
+*Exit:
+*	returns number of characters printed
