Linked list using malloc
Nettet26. mar. 2008 · Linked list is one of the fundamental data structures, and can be used to implement other data structures. In a linked list there are different numbers of nodes. Each node is consists of two fields. The first field holds the value or data and the second field holds the reference to the next node or null if the linked list is empty. Nettet9. aug. 2016 · The malloc (size) function allocates size bytes of memory and returns a pointer to the allocated memory. Our simple malloc will look like: void *malloc(size_t size) { void *block; block = sbrk(size); if (block == (void*) -1) return NULL; return block; } In the above code, we call sbrk () with the given size.
