#define NvBlastAllocaAligned16

(

x

(void*)(((uintptr_t)PxAlloca(x + 0xF) + 0xF) & ~(uintptr_t)0xF)

Stack allocation

#define NvBlastBlockArrayData	(	_dataType,
		_name,
		_accessor,
		_sizeExpr		)

Value:

_dataType* _accessor() const \
{ \
    return (_dataType*)((uintptr_t)this + _name); \
} \
uint32_t _accessor##ArraySize() const \
{ \
    return _sizeExpr; \
} \
uint32_t _name

Block data offset and accessor macro for an array (includes an _accessor#ArraySize() function which returns the last expression).

#define NvBlastBlockData	(	_dataType,
		_name,
		_accessor		)

Value:

_dataType* _accessor() const \
{ \
    return (_dataType*)((uintptr_t)this + _name); \
} \
uint32_t _name

Block data offset and accessor macro.

#define NvBlastCreateOffsetAlign16	(	_name,
		_size		)

Value:

_name = align16(_lastOffset + _lastSize); \
_lastOffset = _name; \
_lastSize = _size

Create the next offset generation with this. The value will be aligned to a 16-byte boundary.

 

#define NvBlastCreateOffsetEndAlign16

(

)

align16(_lastOffset + _lastSize)

End offset generation with this. It evaluates to the (16-byte aligned) total size of the data block.

#define NvBlastCreateOffsetStart

(

_baseOffset

)

Value:

size_t _lastOffset = _baseOffset; \
size_t _lastSize = 0

Block data offset generation macros. Start offset generation with this.
