Macros
#define	OSAPI_ALIGNMENT_DEFAULT   (-1)
	Certain methods allow a default alignment: this should be an alignment that follows the "malloc" alignment of the architecture (aligned sufficiently to store any C-structure efficiently).

Typedefs
typedef RTI_INT32	OSAPI_Alignment_T
	The OSAPIAlignment is the alignment in bytes; an address is aligned when it is a positive integer multiple of the alignment.

Functions
void *	OSAPI_Heap_allocate (RTI_INT32 count, RTI_INT32 size)
	Allocates zero-initialized memory from the heap.
void *	OSAPI_Heap_realloc (void *ptr, RTI_INT32 size)
	Reallocate memory from the heap.
void	OSAPI_Heap_free (void *ptr)
	Frees memory allocated from the heap.
void	OSAPI_Heap_allocate_struct (TYPE **pointer, TYPE)
	Allocates space on the heap for a C structure and initializes the structure with 0's.
void	OSAPI_Heap_free_struct (TYPE *pointer)
	Returns previously allocated (with OSAPI_Heap_allocate_struct) space to the heap.
void	OSAPI_Heap_allocate_array (TYPE **pointer, int count, TYPE)
	A static method to allocate space on the heap for an array of C structures; the array is initialized with 0's.
void	OSAPI_Heap_free_array (TYPE *storage)
	A static method to return space (that was previously allocated with OSAPI_Heap_allocate_array) to the heap.
void	OSAPI_Heap_allocate_string (char **pointer, RTI_UINT32 size)
	A static method to allocate space on the heap for a string of up to a given size. The string is initialized with 0's.
void	OSAPI_Heap_free_string (char *pointer)
	A static method to return space string space to the heap.
void	OSAPI_Heap_allocate_buffer (char **buffer, RTI_UINT32 size, OSAPI_Alignment_T alignment)
	A static method to allocate a block of memory of the provided size from the heap.
void	OSAPI_Heap_free_buffer (void *buffer)
	A static method to return a block (that was previously allocated with OSAPI_Heap_allocate_buffer) to the heap.
RTI_SIZE_T	OSAPI_Heap_get_allocated_byte_count (void)
	Return current allocated memory.
void	OSAPI_Heap_disable_alloc (void)
	Disable memory allocation.

Variables
RTI_SIZE_T	OSAPI_gv_AllocatedByteCount
	Current allocated bytes.
