Macros
#define	ALLOC_MAXTRIES   3
	Max.
#define	ALLOC_DELAY   3
	Delay in seconds between each alloc try.
#define	fmem_alloc(x)
#define	fmem_free(x)

Maybe-free macros
Todo TODO: Think about making what they do more obvious in their identifier, they could be obfuscating their users a little for the newcomers otherwise.

Functions
void *	mem_alloc (size_t)
void *	mem_calloc (size_t, size_t)
void	mem_free (void *)
void *	mem_realloc (void *, size_t)
static int *	intdup__ (int i)

Granular memory allocation.
The granularity used by the aligned memory functions below must be a mask with all bits set from but not including the most significant bit and down. So if an alignment of 256 is wanted use 0xFF.
#define	ALLOC_GR   0x100
	The 'old' style granularity.
#define	ALIGN_MEMORY_SIZE(x, gr)
#define	mem_align_alloc(ptr, old, new_, mask)
static void *	mem_align_alloc__ (void **ptr, size_t old, size_t new_, size_t objsize, size_t mask)
