alloce.txt
Lawrence D. Spencer's replacement functions for debugging memory
allocation errors in C. This file also includes functions to
deal with the file handle problem described at the end of the
article.

baldwin.txt
Listings and examples from Whhab Baldwin's article on generating C
code using AWK. The included program reads a C structure and
produces C code to write a record to a C-ISAM work area.

dudley.txt
Porting a large application to 386 protected mode. Includes a
protected mode function that stuffs draw commands in the draw
list. If the list fills up, it automatically calls pdinterp() to
empty it. Also includes a real mode module callable from protected
mode that passes string in buffer in code segment, and a module to
connect real mode assembly code to prot mode C

dunteman.txt
Jeff Duntemann's SetObject that brings up a 16 X 16 matrix of bit
numbers, each of which corrresponds to one bit in the set. The
method allows the user to zero in on a single bit through the
keyboard or through the mouse if the driver is loaded. Click on
the number (or press Enter) and the bit changes state, as
indicated by screen highlighting. This is useful for debugging or
even data entry to a set object.

eckel.txt
Bruce Eckel's Collection class and example program to count
keywords and identifiers in a C++ source file. The collections
are a good example of multiple inheritance and show the use of
pointers to members.

ellis.txt
Figures, examples, and source code listings from Graham K. Ellis'
article on Parallel Extensions to C. Includes single and two
transputer versions of a multi-process ASCII sorting routine.
Shows how to allocate and deallocate parallel (multi-tasking)
processes on a transputer. The algorithm is modelled after the
sorting example in the INMOS occam Transputer Development System
(TDS).

ladd.txt
Listings from Scott Ladd's review of Microsoft C 6.0. Includes
some of the benchmarks mentioned in the article, which compare
MSC 6.0 to Watcom 7.0. Also includes Bruce Schatzman's example
using based pointers.

lauzzana.txt
Mixed-language programming article using Lisp and C to generate a
spline function that uses the Macintosh Toolbox to draw smooth
curves.

mak.txt
Source code for OS2ERR, an error tracking utility for OS/2's (somtimes)
cryptic error messages. When a function returns an error the utility
displays a pop-up screen with info on the program name, process
ID, thread ID, error code and error ID. The utility also
recommends an action to be taken and gives you the choice of
continuing or aborting the offending program.

mischel.txt
Source code from Jim Mischel's article on extending printf() to
output formatted numbers. Includes support for variable argument
lists.

schimand.txt
Source to the dynamic memory handler described in Jim Schimandle's
article "Encapsulating C Memory Allocation"

spencer.txt
Lawrence D. Spencer's replacement functions for debugging memory
allocation errors in C. See ALLOCE.ALL for this same file plus the
"freebie" functions mentioned at the end of the article.

stevens.txt
Listings from Al Stevens' C Programming colomn which covers the
NetWare programming environment.
