Function Documentation

SanitizerResult SANITIZERAPI sanitizerAlloc	(	CUcontext	ctx,
		void **	devPtr,
		size_t	size
	)

Equivalent of cudaMalloc that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

	ctx	Context for the allocation. If NULL, the current context will be used.
	devPtr	Pointer to allocated device memory
	size	Allocation size in bytes

SanitizerResult SANITIZERAPI sanitizerFree	(	CUcontext	ctx,
		void *	devPtr
	)

Equivalent of cudaFree that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

	ctx	Context for the allocation. If NULL, the current context will be used.
	devPtr	Device pointer to memory to free

SanitizerResult SANITIZERAPI sanitizerMemcpyDeviceToHost	(	void *	dst,
		void *	src,
		size_t	count,
		Sanitizer_StreamHandle	stream
	)

Equivalent of cudaMemcpy that can be called within a callback function. The function will return once the copy has completed. If the function is called from a SANITIZER_CB_DOMAIN_LAUNCH callback, only pinned host memory may be used as destination.

Note:

Thread-safety: this function is thread safe.

Parameters:

	dst	Destination memory address
	src	Source memory address
	count	Size in bytes to copy
	stream	Stream handle. If NULL, the NULL stream will be used.

SanitizerResult SANITIZERAPI sanitizerMemcpyHostToDeviceAsync	(	void *	dst,
		void *	src,
		size_t	count,
		Sanitizer_StreamHandle	stream
	)

Equivalent of cudaMemcpyAsync that can be called within a callback function. The function will return once the pageable buffer has been copied to the staging memory for DMA transfer to device memory, but the DMA to final destination may not have completed.

Note:

Thread-safety: this function is thread safe.

Parameters:

	dst	Destination memory address
	src	Source memory address
	count	Size in bytes to copy
	stream	Stream handle. If NULL, the NULL stream will be used.

SanitizerResult SANITIZERAPI sanitizerMemset	(	void *	devPtr,
		int	value,
		size_t	count,
		Sanitizer_StreamHandle	stream
	)

Equivalent of cudaMemset that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

	devPtr	Pointer to device memory
	value	value to set for each byte of specified memory
	count	Size in bytes to set
	stream	Stream handle. If NULL, the NULL stream will be used.
