Function Documentation

◆ rtl_allocateAlignedMemory()

SAL_DLLPUBLIC void* rtl_allocateAlignedMemory	(	sal_Size	Alignment,
		sal_Size	Bytes
	)

Allocate aligned memory.

A call to this function will return NULL upon the requested memory size being either zero or larger than currently allocatable.

Memory obtained through this function must be freed with rtl_freeAlignedMemory().

Parameters

[in]	Alignment	alignment in bytes, must be a power of two multiple of sizeof(void*).
[in]	Bytes	memory size.

Returns: pointer to the allocated memory.

Since: LibreOffice 4.3

◆ rtl_allocateMemory()

SAL_DLLPUBLIC void* rtl_allocateMemory ( sal_Size Bytes )

Parameters

[in] Bytes memory size.

Returns: pointer to the allocated memory.

◆ rtl_allocateZeroMemory()

SAL_DLLPUBLIC void* rtl_allocateZeroMemory ( sal_Size Bytes )

Allocate and zero memory.

A call to this function will return NULL upon the requested memory size being either zero or larger than currently allocatable.

Parameters

[in] Bytes memory size.

Returns: pointer to the allocated and zero'ed memory.

◆ rtl_arena_alloc()

SAL_DLLPUBLIC void* rtl_arena_alloc	(	rtl_arena_type *	pArena,
		sal_Size *	pBytes
	)

Parameters

[in]	pArena	arena from which resource is allocated.
[in,out]	pBytes	size of resource to allocate.

Returns: allocated resource, or NULL upon failure.

◆ rtl_arena_create()

SAL_DLLPUBLIC rtl_arena_type* rtl_arena_create	(	const char *	pName,
		sal_Size	quantum,
		sal_Size	quantum_cache_max,

		void ()(rtl_arena_type , sal_Size )	source_alloc,
		void()(rtl_arena_type , void *, sal_Size)	source_free,
		int	nFlags
	)

Parameters

[in]	pName	descriptive name; for debugging purposes.
[in]	quantum	resource allocation unit / granularity; rounded up to next power of 2.
[in]	quantum_cache_max	no longer used, should be 0.
[in]	source_arena	passed as argument to source_alloc, source_free; usually NULL.
[in]	source_alloc	function to allocate resources; usually rtl_arena_alloc.
[in]	source_free	function to free resources; usually rtl_arena_free.
[in]	nFlags	flags; usually 0.

Returns: pointer to rtl_arena_type, or NULL upon failure.

◆ rtl_arena_destroy()

SAL_DLLPUBLIC void rtl_arena_destroy ( rtl_arena_type * pArena )

Parameters

[in] pArena the arena to destroy.

See also: rtl_arena_create()

◆ rtl_arena_free()

SAL_DLLPUBLIC void rtl_arena_free	(	rtl_arena_type *	pArena,
		void *	pAddr,
		sal_Size	nBytes
	)

Parameters

[in]	pArena	arena from which resource was allocated.
[in]	pAddr	resource to free.
[in]	nBytes	size of resource.

◆ rtl_cache_alloc()

SAL_DLLPUBLIC void* rtl_cache_alloc ( rtl_cache_type * pCache )

Parameters

[in] pCache cache from which object is allocated.

Returns: pointer to the allocated object, or NULL upon failure.

◆ rtl_cache_create()

[in]	nObjSize	object size.
[in]	nObjAlign	object alignment; usually 0 for suitable default.
[in]	constructor	object constructor callback function; returning 1 for success or 0 for failure.
[in]	destructor	object destructor callback function.
[in]	reclaim	reclaim callback function.
[in]	pUserArg	opaque argument passed to callback functions.
[in]	pSource	unused argument (should be null).
[in]	nFlags	flags (unused).

Returns: pointer to rtl_cache_type, or NULL upon failure.

◆ rtl_cache_destroy()

SAL_DLLPUBLIC void rtl_cache_destroy ( rtl_cache_type * pCache )

Parameters

[in] pCache the cache to destroy.

See also: rtl_cache_create()

◆ rtl_cache_free()

SAL_DLLPUBLIC void rtl_cache_free	(	rtl_cache_type *	pCache,
		void *	pObj
	)

Parameters

[in]	pCache	cache from which object was allocated.
[in]	pObj	object to free.

See also: rtl_cache_alloc()

◆ rtl_freeAlignedMemory()

SAL_DLLPUBLIC void rtl_freeAlignedMemory ( void * Ptr )

Free memory allocated with rtl_allocateAlignedMemory().

Memory is released, and the pointer invalidated.

Parameters

[in] Ptr pointer to the previously allocated memory.

Since: LibreOffice 4.3

◆ rtl_freeMemory()

SAL_DLLPUBLIC void rtl_freeMemory ( void * Ptr )

Free memory.

Memory is released, and the pointer is invalidated.

Parameters

[in] Ptr pointer to the previously allocated memory.

◆ rtl_freeZeroMemory()

SAL_DLLPUBLIC void rtl_freeZeroMemory	(	void *	Ptr,
		sal_Size	Bytes
	)

Zero and free memory.

Memory is zero'ed with rtl_secureZeroMemory() and released. The original pointer is no longer valid.

Parameters

[in]	Ptr	pointer to the previously allocated memory.
[in]	Bytes	memory size.

◆ rtl_reallocateMemory()

SAL_DLLPUBLIC void* rtl_reallocateMemory	(	void *	Ptr,
		sal_Size	Bytes

Reallocate memory.

A call to this function with parameter 'Ptr' being NULL is equivalent to a rtl_allocateMemory() call. A call to this function with parameter 'Bytes' being 0 is equivalent to a rtl_freeMemory() call.

See also: rtl_allocateMemory(); rtl_freeMemory()

Parameters

[in]	Ptr	pointer to the previously allocated memory.
[in]	Bytes	new memory size.

Returns: pointer to the reallocated memory. May differ from Ptr.

◆ rtl_secureZeroMemory()

		sal_Size	Bytes
	)

Zero memory.

Fills a block of memory with zeros in a way that is guaranteed to be secure

Parameters

[in]	Ptr	pointer to the previously allocated memory.
[in]	Bytes	memory size.

Since: LibreOffice 5.0
