Memory Allocation Routines

Routine	Attributes	Description
calloc		Allocates storage for an array from the memory pool.
free		Frees a memory block that was allocated using calloc, malloc, or realloc.
init_mempool		Initializes the memory location and size of the memory pool.
malloc		Allocates a block from the memory pool.
realloc		Reallocates a block from the memory pool.

Use the memory allocation functions to specify, allocate, and free blocks of memory from a memory pool. All memory allocation functions are implemented as functions and are prototyped in the stdlib.h include file.

Before using any of these functions to allocate memory, you must first specify the size and location of the memory pool using the init_mempool routine. All memory requests are satisfied using this memory block.

The calloc and malloc routines allocate blocks of memory from the pool. The calloc routine allocates an array with a specified number of elements of a given size and initializes the array to 0. The malloc routine allocates a specified number of bytes.

The realloc routine changes the size of an allocated block while the free routine returns a previously allocated memory block to the memory pool.
