Design the skeleton of the advanced final mini app.
Project: Mini server
In this five-lesson project you'll build a mini server. Each lesson adds a layer; by the final lesson you'll have a working program that combines fork/pthread, sockets and IPC.
You'll use what you learned in earlier groups: fork, pthread, sockets and pipe. Throughout the project you'll define four functions: worker_init, server_setup, ipc_setup and server_run. In this first lesson you'll lay out the module skeleton: prototypes and main.
Module skeleton
Large C projects start with prototypes. int worker_init(void); is a declaration; the definition may be in another file or below. With the declaration the compiler knows the function exists.
In this project you'll define four prototypes: worker_init (process/thread layer), server_setup (socket layer), ipc_setup (IPC layer) and in the final lesson server_run (integration). The first lesson starts with only the first three prototypes and a main that prints printf("Proje hazır\n");.
Practice Write the skeleton
Add three prototypes: int worker_init(void);, int server_setup(void);, int ipc_setup(void);. Write int main(void) and inside it print printf("Proje hazır\n");.
Starter code
#include <stdio.h>
// Proje: mini sunucu (fork/pthread + soket + IPC)
// worker_init, server_setup, ipc_setup prototiplerini ekle
// main: "Proje hazır" yazdırSample solution
#include <stdio.h>
int worker_init(void);
int server_setup(void);
int ipc_setup(void);
int main(void) {
printf("Proje hazır\n");
return 0;
}Expected output
Proje hazır
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 Which layers does the project include?
- Only printf
- Only file I/O
- Process + socket + IPC Correct answer
- Only loops
Explanation: The project combines fork/pthread, socket and IPC layers.
2 worker_init prototype
int worker_init(____);int worker_init(void);Explanation: worker_init(void) is a parameterless function.
