Macro Definition Documentation

NewMem

#define NewMem	(		T,
			cnt
	)

Allocates raw memory: no constructors are called! A valid memory address will be returned if cnt is 0 (unless there was not enough memory).

Note

This behaviour was different in Cinema 4D where nullptr was returned. THREADSAFE.

Parameters

[in]	T	Type of item (e.g. Char, Float)
[in]	cnt	Number of items.

Returns

Pointer to memory block or nullptr.

NewMemClear

#define NewMemClear	(		T,
			cnt
	)

Allocates raw memory and clears it: no constructors are called! THREADSAFE.

Parameters

[in]	T	Type of item (e.g. Char, Float)
[in]	cnt	Number of items.

Returns

Pointer to memory block or nullptr.

ReallocMem

#define ReallocMem	(		p,
			cnt
	)

Resizes a raw memory block : no constructors are called! The content of the memory block is preserved up to the lesser of the new and old sizes, even if the block is moved to a new location. The additional memory is not cleared, it may contain a certain byte pattern in debug mode. In case that p is a nullptr the function behaves like NewMem. If the function fails to allocate the requested block of memory a nullptr is returned and the memory block pointed to by argument p is not deallocated (it is still valid with its contents unchanged). THREADSAFE.

Parameters

[in]	p	Current memory block (can be nullptr)
[in]	cnt	New number of items (size of the memory block is n * sizeof(T))

Returns

Memory block address or nullptr if resize is not possible (p is still valid in this case)
