My Heap

Small quick project based on what we learnt in class. Allows the user to create a heap memory with a specified size and then allows to store data on that heap with matadata. Then allows those blocks to be deallocated and merged later.

Usage

// creates a heap with 256 allocated bytes
struct myheap* h = heapCreate(256);

// allocates memory on that heap
int* arr1 = myheapMalloc(h, sizeof(int) * 5);
int* arr2 = myheapMalloc(h, sizeof(int) * 10);

// data modification
arr1[0] = 1;
arr1[1] = 2;
arr1[2] = 3;

arr2[3] = 3;
arr2[6] = 2;
arr2[9] = 1;

// frees the data
myheapFree(h, arr1);
myheapFree(h, arr2);

Useful Feature

printBlocks(h);
