TITLE: C-ACROSS;
VERSION 1.02
DESCRIPTION: "Utility for multiple module programs. Produces
Six indexes of functions, prototypes, and globals that
enable user to 'see across' modules for use in checking
and comparison. One of these is type of hierarchical
functions list, a listing by module of functions
and calls made FROM them; another is alphabetical list
of functions and calls made TO them. Globals listed
in schematic descriptors which record all modifiers
and qualifiers and enable checking of declarators
across modules. Creates, on request, header file
consisting of prototypes constructed from function
definitions. Can list user types #defined and some
preprocessor #defines. Full documentation in README.CA";
KEYWORDS: Utility, Cross Reference, Deubgging;
SYSTEM: MS-DOS;
FILENAME: INTF_CA.C;
WARNINGS: "1. Assumes function definitions conform with
ANSI standards and have prototype form. See
also "Caveats and Restrictions" in README.CA.
2. Assumes syntactically correct source files.
3. Written and tested using Microsoft QuickC.
4. Copyright retained. See Copyright
information in README.CA.";
