o Malloc – Allocating memory in multiples of header size – Finding the first typedef long Align; union header { /* block header */ struct { union header *ptr;

malloc allocates a block of memory of the requested size Returns a pointer to the first byte of that memory And returns NULL if the memory allocation failed

Lecture 5 - malloc, free, struct, typedef So far, we have seen two kinds of memory allocation: malloc returns NULL if the memory could not be allocated

Struct declaration allocates a contiguous memory for the collection day windDirection malloc C Library (stdlib h) function for allocating memory at run- time

[PDF] C Dynamic Data Structures - UT Austin Computer Science

The Standard C Library provides a function for allocating memory at run-time: malloc void *malloc(int numBytes); It returns a generic pointer (void*) to a contiguous region of memory of the requested size (in bytes) The bytes are allocated from a region in memory called the heap
