.source	__FILE__

/	Allocates uninitialized memory.
/
/	Returns a pointer to a newly allocated chunk of at least n bytes, or
/	null if no space is available, in which case errno is set to ENOMEM
/	on ANSI C systems.
/
/	If n is zero, malloc returns a minimum-sized chunk. (The minimum size
/	is 32 bytes on 64bit systems.) Note that size_t is an unsigned type,
/	so calls with arguments that would be negative if signed are
/	interpreted as requests for huge amounts of space, which will often
/	fail. The maximum supported value of n differs across systems, but is
/	in all cases less than the maximum representable value of a size_t.
/
/	@param	rdi is number of bytes needed
/	@return	new memory, or NULL w/ errno
/	@note	malloc(0) → malloc(32)
/	@see	dlmalloc()
