+*fscanf.c - read formatted data from stream
+*
+* Copyright (c) 1985-1991, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+* defines fscanf() - reads formatted data from stream
+*
+*Revision History:
+* 09-02-83 RN initial version
+* 04-13-87 JCR added const to declaration
+* 06-24-87 JCR (1) Made declaration conform to ANSI prototype and use
+* the va_ macros; (2) removed SS_NE_DS conditionals.
+* 11-06-87 JCR Multi-thread support
+* 12-11-87 JCR Added "_LOAD_DS" to declaration
+* 05-31-88 PHG Merged DLL and normal versions
+* 02-15-90 GJF Fixed copyright and indents
+* 03-19-90 GJF Replaced _LOAD_DS with _CALLTYPE2 and added #include
+* <cruntime.h>.
+* 03-26-90 GJF Added #include <internal.h>.
+* 07-23-90 SBM Replaced <assertm.h> by <assert.h>
+* 10-02-90 GJF New-style function declarator.

+*Entry:

+* followed by list of pointers to storage for the data read. The number
+* and type are controlled by the format string.
