arena -- Definition

An arena is the area of  memory that is available for a program to allocate
dynamically  at run  time.  It  is divided  into allocated  and unallocated
blocks.  The unallocated blocks together form the ``free-memory pool''.

To allocate  a portion  of the  arena, use any  of the  functions malloc(),
calloc(), or  realloc(). To  return an allocated  portion of memory  to the
free-memory pool, use the function free(). To check whether a given portion
of  the arena  is already  allocated, use the  function notmem().  To check
whether the arena has been corrupted, use the function memok().
