Expert Solution & Answer
Chapter 12, Problem 12.36HW
Explanation of Solution
Implementation of a concurrent prethreaded version of the TINY web server:
For code “echoservers.c” and “echoservers.h” file:
Use section 12.2.1 code.
For code “tiny.c” and “tiny.h”:
Use section 11.6 code.
sample.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Home</title>

</html>
main.c:
#include <stdio.h>
#include "csapp.h"
#include "echoservers.h"
//Main function
int main(int argc, char **argv)
{
//Declare variable
int listenfd, connfd;
socklen_t clientlen;
struct sockaddr_storage clientaddr;
static pool pool;
/* If the arguments does not contain two arguments, then display the below statement */
if (argc != 2)
{
fprintf(stderr, "usage: %s <port>\n", argv[0]);
fprintf(stderr, "use default port 5000\n");
listenfd = Open_listenfd("5000");
}
//Otherwise call Open_listenfd function
else
{
listenfd = Open_listenfd(argv[1]);
}
//Then call the init_pool function
init_pool(listenfd, &pool);
//Check condition
while (1)

Programming Problems
9.28
Assume that a system has a 32-bit virtual address with a 4-KB page size.
Write a C program that is passed a virtual address (in decimal) on the
command line and have it output the page number and offset for the
given address. As an example, your program would run as follows:
./addresses 19986
Your program would output:
The address 19986 contains:
page number = 4
offset = 3602
Writing this program will require using the appropriate data type to
store 32 bits. We encourage you to use unsigned data types as well.
Programming Projects
Contiguous Memory Allocation
In Section 9.2, we presented different algorithms for contiguous memory allo-
cation. This project will involve managing a contiguous region of memory of
size MAX where addresses may range from 0 ... MAX - 1. Your program must
respond to four different requests:
1. Request for a contiguous block of memory
2. Release of a contiguous block of memory
3. Compact unused holes of memory into one single block
4.…
