alloc()

def miasm.os_dep.common.heap.alloc	(		self,
			jitter,
			size,
			perm = PAGE_READ | PAGE_WRITE,
			cmt = ""
	)

@jitter: a jitter instance
@size: the size to allocate
@perm: permission flags (see vm_alloc doc)

Here is the call graph for this function:

get_size()

def miasm.os_dep.common.heap.get_size	(		self,
			vm,
			ptr
	)

@vm: a VmMngr instance
@size: ptr to get the size of the associated allocation.

`ptr` can be the base address of a previous allocation, or an address
within the allocated range. The size of the whole allocation is always
returned, regardless ptr is the base address or not.

Here is the caller graph for this function:

next_addr()

def miasm.os_dep.common.heap.next_addr	(		self,
			size
	)

@size: the size to allocate
return the future checnk address

Here is the caller graph for this function:

vm_alloc()

def miasm.os_dep.common.heap.vm_alloc	(		self,
			vm,
			size,
			perm = PAGE_READ | PAGE_WRITE,
			cmt = ""
	)

@vm: a VmMngr instance
@size: the size to allocate
@perm: permission flags (PAGE_READ, PAGE_WRITE, PAGE_EXEC or any `|`
    combination of them); default is PAGE_READ|PAGE_WRITE

Here is the call graph for this function:
