Function Documentation

InitAmigaAllocator()

void InitAmigaAllocator

(

void

)

Initialise the memory allocator for Amiga OS4.

ExitAmigaAllocator()

void ExitAmigaAllocator

(

void

)

Free any resources used by the memory allocator for AmigaOS 4.x.

AllocateAmigaMemory()

void* AllocateAmigaMemory

(

uint32

size

)

Allocate a block of memory of the given size on AmigaOS 4.x.

Parameters

size	The size of the required memory block in bytes.

Returns

The uninitialised memory block or NULL upon error.

AllocateAmigaZeroedArray()

void* AllocateAmigaZeroedArray	(	uint32	num_elements,
		uint32	size
	)

Allocate an array of memory blocks on AmigaOS 4.x.

Parameters

num_elements	The number of memory blocks to allocate.
size	The size of each of the required memory block in bytes.

Returns

The memory blocks which have all been initialised to 0 or NULL upon error.

ReallocateAmigaMemory()

void* ReallocateAmigaMemory	(	void *	old_p,
		uint32	new_size,
		uint32	old_size
	)

Reallocate a memory block on AmigaOS 4.x.

The values will be copied from the old block to the new one if required whilst respecting buffer limits.

Parameters

old_p	The memory block to reallocate.
new_size	The size of the new memory block.
old_size	The size of the old memory block.

Returns

The reallocated memory block or NULL upon error.

FreeAmigaMemory()

void FreeAmigaMemory

(

void *

mem_p

)

Free some memory created by AllocAmigaMemory() or AllocAmigaMemoryArray()

Parameters

mem_p

The memory block to free.
