Detailed Description
\brief deprecated memory management functions of the CUDA runtime API (cuda_runtime_api.h)
This section describes deprecated memory management functions of the CUDA runtime application programming
interface.
Some functions have overloaded C++ API template versions documented separately in the C++ API Routines
module.
Function Documentation
__CUDA_DEPRECATED cudaError_t cudaMemcpyArrayToArray (cudaArray_t dst, size_t wOffsetDst, size_t hOffsetDst,
cudaArray_const_t src, size_t wOffsetSrc, size_t hOffsetSrc, size_t count, enum cudaMemcpyKind kind =
cudaMemcpyDeviceToDevice)
Deprecated
Copies count bytes from the CUDA array src starting at the upper left corner (wOffsetSrc, hOffsetSrc) to
the CUDA array dst starting at the upper left corner (wOffsetDst, hOffsetDst) where kind specifies the
direction of the copy, and must be one of cudaMemcpyHostToHost, cudaMemcpyHostToDevice,
cudaMemcpyDeviceToHost, cudaMemcpyDeviceToDevice, or cudaMemcpyDefault. Passing cudaMemcpyDefault is
recommended, in which case the type of transfer is inferred from the pointer values. However,
cudaMemcpyDefault is only allowed on systems that support unified virtual addressing.
Parameters:
dst - Destination memory address
wOffsetDst - Destination starting X offset
hOffsetDst - Destination starting Y offset
src - Source memory address
wOffsetSrc - Source starting X offset
hOffsetSrc - Source starting Y offset
count - Size in bytes to copy
kind - Type of transfer
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidMemcpyDirection
Note:
Note that this function may also return error codes from previous, asynchronous launches.

__CUDA_DEPRECATED cudaError_t cudaMemcpyFromArray (void * dst, cudaArray_const_t src, size_t wOffset, size_t
hOffset, size_t count, enum cudaMemcpyKind kind)
Deprecated
Copies count bytes from the CUDA array src starting at the upper left corner (wOffset, hOffset) to the
memory area pointed to by dst, where kind specifies the direction of the copy, and must be one of
cudaMemcpyHostToHost, cudaMemcpyHostToDevice, cudaMemcpyDeviceToHost, cudaMemcpyDeviceToDevice, or
cudaMemcpyDefault. Passing cudaMemcpyDefault is recommended, in which case the type of transfer is
inferred from the pointer values. However, cudaMemcpyDefault is only allowed on systems that support
unified virtual addressing.
Parameters:
dst - Destination memory address
src - Source memory address
wOffset - Source starting X offset
hOffset - Source starting Y offset
count - Size in bytes to copy
kind - Type of transfer
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidMemcpyDirection
Note:
Note that this function may also return error codes from previous, asynchronous launches.
This function exhibits behavior for most use cases.

__CUDA_DEPRECATED cudaError_t cudaMemcpyFromArrayAsync (void * dst, cudaArray_const_t src, size_t wOffset,
size_t hOffset, size_t count, enum cudaMemcpyKind kind, cudaStream_t stream = 0)
Deprecated
Copies count bytes from the CUDA array src starting at the upper left corner (wOffset, hOffset) to the
memory area pointed to by dst, where kind specifies the direction of the copy, and must be one of
cudaMemcpyHostToHost, cudaMemcpyHostToDevice, cudaMemcpyDeviceToHost, cudaMemcpyDeviceToDevice, or
cudaMemcpyDefault. Passing cudaMemcpyDefault is recommended, in which case the type of transfer is
inferred from the pointer values. However, cudaMemcpyDefault is only allowed on systems that support
unified virtual addressing.
cudaMemcpyFromArrayAsync() is asynchronous with respect to the host, so the call may return before the
copy is complete. The copy can optionally be associated to a stream by passing a non-zero stream
argument. If kind is cudaMemcpyHostToDevice or cudaMemcpyDeviceToHost and stream is non-zero, the copy
may overlap with operations in other streams.
Parameters:
dst - Destination memory address
src - Source memory address
wOffset - Source starting X offset
hOffset - Source starting Y offset
count - Size in bytes to copy
kind - Type of transfer
stream - Stream identifier
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidMemcpyDirection
Note:
Note that this function may also return error codes from previous, asynchronous launches.
This function exhibits behavior for most use cases.
This function uses standard semantics.
