README

Objective

The objective of this project is have the server to load a text file into file-backed shared memory which allows the client to change any lower case characters to upper case.

Included Files

The project includes the following files:

• makefile
• text-server.c
• text-client.c
• text-memory.c
• README.md

Makefile

When make is executed in the terminal. The make file executes two commands.

gcc -o text-client text-client.c

gcc -o text-server text-server.c

When make clean is executed in the terminal. The make file removes any executable or intermediary build files created by make. It is done using the following command in bash.

rm -rf text-client text-server *.o

Server

To run the server a command in the following format must be entered.

./text-server

The server will start and display that it started.

Everytime a client connects:

• The server will log the client's request, memory segment opening, filename, file closing, and memory closing.
• If the server is successfully able to open the file, the it will send a signal to the client to make changes.

Client

A client can be started by entering a command in the following format.

./text-client dat/dante.txt

The client will start, parse text using four threads, and replace any lower-case characters with its upper-case version.

Everytime a client connects:

• The client will send a filename to the server.
• After the server is able to open the file and load the file into file-backed shared memory, the client starts the conversion process using threads.
• The client uses 4 threads.

Header Files

For this project, text-memory.h is created primarily to contain any used libraries and globally defined values.
