Macro Definition Documentation

◆  __C4D_MEM_ALIGNMENT_MASK__

#define __C4D_MEM_ALIGNMENT_MASK__

Memory returned by NewMem() is guaranteed to be at least aligned to a 16 byte boundary.

◆  FillMemType

#define FillMemType	(		t,
			d,
			x,
			v
	)

Fills a block of memory of the specified type.

参数

[in]	t	Data type (e.g. Char, Float).
[out]	d	Address of the block of memory to fill. The caller owns the pointed memory.
[in]	x	Size of the memory block to fill.
[in]	v	Value to fill the memory block with.

◆  GeMemGetFreePhysicalMemoryEstimate()

UInt GeMemGetFreePhysicalMemoryEstimate

(

)

Gets estimated free physical memory.

返回

Estimated free physical memory.

◆  ClearMem()

void ClearMem	(	void *	d ,
		Int	size ,
		Int32	value = 0
	)

Clears a block of memory.

参数

[in]	d	Address of the memory block to clear. The caller owns the pointed memory.
[in]	size	Size in bytes of the block of memory to clear.
[in]	value	Value to clear the memory block with. Default to 0 .

◆  CopyMem()

void CopyMem	(	const void *	s ,
		void *	d ,
		Int	size
	)
