- Use the programs in this directory to explore the features of the
- Pacific C compiler.
-
- MAKEALL.BAT MS-DOS batch file which compiles all of the programs
- in this directory in one hit.
-
- ARGS.C demonstrates use of the "argc" and "argv" parameters
- to main() to iterate through command line arguments
- to a program. You can also use this program to test
- the effect of the PACC "-R" option and the PPD option
- "_getargs() wildcard expansion".
-
- CHK.C simple file checksum utility. Generates a 32-bit
- checksum for each file passed on the command line.
-
- EXITFUNC.C demonstrates use of the atexit() function to install
- a user function which will be automatically executed
- when your program terminates.
-
- FCALC.C simple floating point calculator program. Compile
- with "Use floating point library" enabled in PPD, or
- the PACC -lf option. For better performance with a
- floating point co-processor, enable hardware floating
- point in the "Memory model and chip type ..." dialog
- or use the PACC -7 option.
-
- FULLPATH.C demonstrates the use of the _fullpath global variable
- to determine the directory and name of the currently
- executing program. This program should be compiled
- using the LARGE memory model because _fullpath is not
- available in the small model library.
-
- HELLO.C the infamous hello world program known to programmers
- everywhere!
-
- HEXD.C a handy HEX dump utility which you can use to examine
- binary files and other mysteries. Uses <stdio.h>
- functions to read input files, uses argc and argv
- to process the command line arguments.
-
- KEYRATE.C another useful utility, which can be used to set the
- typematic rate (repeat speed and delay) on PC/AT type
- keyboards. Demonstrates the use of Pacific C "port"
- variables to perform hardware specific tasks.
-
- MOUSE.C Pacific C mouse driver "glue" code. This is not a
- standalone program, it should be compiled to .OBJ
- and linked with user application code. The header
- file "mouse.h" contains the extern declarations for
- the routines and data structures contained in MOUSE.C
- The routines in this module can be used to interface
- to any standard mouse driver which uses the INT 33H
- interface. To compile MOUSE.C use the PACC command
- PACC -O -Zg -C MOUSE.C or the PPD "Compile to OBJ" menu
- item.
-
- MOUSE.H header file for MOUSE.C routines. Examine this file
- to determine what mouse functions are available.
-
- MOUSEX.C example code using the MOUSE.C interface routines.
- Use this as the starting point for your own mouse
- driven applications. To compile using PACC, use the
- command PACC MOUSEX.C MOUSE.OBJ. To compile with PPD,
- use the MOUSEX.PRJ multi-file project.
-
- MOUSEX.PRJ PPD project file used to compile MOUSEX.C and MOUSE.C
- together as a single project. Use this a a starting
- point for your own multi-file projects. If you did not
- install Pacific C in the default C:\PACIFIC directory, you
- may need to manually edit some of the path names in
- this file. Do not edit this MOUSEX.PRJ with the MS-DOS
- EDIT command because EDIT converts tabs to spaces!
-
- PRINTENV.C demonstrates use of the getenv() function to return
- the value of a DOS environment variable. Also gives
- an example of how to iterate through the command line
- arguments passed to main
-
- QSORTEX.C contains example code using the qsort() function to
- sort the contents of an array.
-
- READDIR.C gives an example of a practical use of the intdos()
- function to read an MS-DOS directory. The user gives
- a search wildcard and the function putdir() will print
- all matches.
-
- READDIR2.C is an alternative version of READDIR.C which uses the
- msdos() function instead of intdos(). Note the use of
- variable arguments with msdos() so only those arguments
- actually required are passed.
-
- SIEVE.C is an implementation of the Sieve of Eratosthenes prime
- number generator.
-
- TALK.C is the most complex of the demonstration programs. It
- is a simple terminal program which directly drives the
- PC serial ports. The serial port driver in talk is an
- example of the the use of port variables and interrupt
- functions to write an interrupt driven device driver.
-
- U2D.C UNIX to DOS text file conversion utility. Converts UNIX
- style text files with only newline (0AH) characters on
- the end of lines to DOS style text files.
-
- USAGE.C utility which calculates the amount of disk space used
- by a group of files or directories. Includes recursive
- directory scanning code which could be used as the core
- of an "XTREE" type utility. Exercise: modify the code
- to determine the block size of the disk using MS-DOS
- calls instead of requiring block size as a user option.
