Function Documentation

orxDLLAPI void* orxFASTCALL orxMemory_Allocate	(	orxU32	_u32Size,
		orxMEMORY_TYPE	_eMemType
	)

Allocates a portion of memory in the system and returns a pointer on it

Parameters:

[in]	_u32Size	Size of the memory to allocate
[in]	_eMemType	Memory zone where datas will be allocated

Returns:

returns a pointer on the memory allocated, or orxNULL if an error has occured

orxDLLAPI orxU32 orxFASTCALL orxMemory_Compare	(	const void *	_pMem1,
		const void *	_pMem2,
		orxU32	_u32Size
	)

Compares two portions of memory

Parameters:

[in]	_pMem1	First potion to test
[in]	_pMem2	Second portion to test
[in]	_u32Size	Size of data to test

Returns:

returns a value less, equals or greater that 0 if _pMem1 is respectively smaller, equal or greater than _pMem2

orxDLLAPI void* orxFASTCALL orxMemory_Copy	(	void *	_pDest,
		const void *	_pSrc,
		orxU32	_u32Size
	)

Copies a portion of memory into another one

Parameters:

[out]	_pDest	Destination pointer
[in]	_pSrc	Pointer of memory from where data are read
[in]	_u32Size	Size of data

Returns:

returns a pointer on _pDest

Note:

if _pSrc and _pDest overlap, use orxMemory_Move instead

orxDLLAPI void orxFASTCALL orxMemory_Exit

(

)

Exits from the memory module

orxDLLAPI void orxFASTCALL orxMemory_Free

(

void *

_pMem )

Frees a portion of memory allocated with orxMemory_Allocate

Parameters:

[in]

_pMem

Pointer on the memory allocated by orx

orxDLLAPI orxSTATUS orxFASTCALL orxMemory_Init

(

)

Inits the memory module

Returns:

orxSTATUS_SUCCESS / orxSTATUS_FAILURE

orxDLLAPI void* orxFASTCALL orxMemory_Move	(	void *	_pDest,
		void *	_pSrc,
		orxU32	_u32Size
	)

Moves a portion of memory into another one

Parameters:

[out]	_pDest	Destination pointer
[in]	_pSrc	Pointer of memory from where data are read
[in]	_u32Size	Size of data

Returns:

returns a pointer on _pDest

orxDLLAPI void* orxFASTCALL orxMemory_Reallocate	(	void *	_pMem,
		orxU32	_u32Size
	)

Reallocates a portion of memory if the already allocated memory is not suffisant.

Parameters:

[in]	_pMem	Memory to reallocate.
[in]	_u32Size	Wanted size.

Returns:

The pointer reallocated.

orxDLLAPI void* orxFASTCALL orxMemory_Set	(	void *	_pDest,
		orxU8	_u8Data,
		orxU32	_u32Size
	)

Fills a portion of memory with _u32Data

Parameters:

[out]	_pDest	Destination pointer
[in]	_u8Data	Values of the data that will fill the memory
[in]	_u32Size	Size of data

Returns:

returns a pointer on _pDest

orxDLLAPI void orxFASTCALL orxMemory_Setup

(

)

Setups the memory module

orxDLLAPI void* orxFASTCALL orxMemory_Zero	(	void *	_pDest,
		orxU32	_u32Size
	)

Fills a portion of memory with zeroes

Parameters:

[out]	_pDest	Destination pointer
[in]	_u32Size	Size of data

Returns:

returns a pointer on _pDest
