COSC1112 - Operating Systems - Programming - Management Assessment Answer 

Assessment Task:

Assignment 1 – Segmented Memory Allocator
To a large extent, programming is about management of memory as it’s one of the key resources that we have at our disposal as programmers.
What we want you to consider is the costs involved in the memory allocation strategies you’re going to implement. We want you to gain an appreciation of the complexity of memory allocation and the fact it is not a cost free process. We would certainly not advise you to reimplement your own memory allocator unless you find in a particular project you have certain needs. Please note that you may choose to implement your solution to this task in C or in C++ as that shouldn’t matter.

Programming Task
The System Calls The basic system calls used to allocate memory and free memory in UNIX-like operating systems are brk() and sbrk(). These functions allocate and deallocate memory by shifting the “program break” or heap frontier up and down. The heap starts at low addresses and so shifting the program break upwards allocates memory and shifting it downwards deallocates memory. function prototypes for these are:

int brk(void * addr); This function sets the program break to be the value passed in by addr. If the setting of these values is successful, brk() will return 0. void * sbrk(intptr_t increment);
adds or subtracts from the current program break to allocate memory (if a positive number is provided) and to free memory if a negative number is provided.
In this assignment you will use these functions to allocate memory. We won’t be using these functions to free memory as that’s a bit more complicated a proposition.
