50 Module Documentation hOffset - Source starting Y offset count - Size in bytes to copy kind - Type of transfer stream - Stream identifier Returns: Note: See also: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer, cudaErrorInvalidMemcpyDirection Note that this function may also return error codes from previous, asynchronous launches. cudaMemcpy, cudaMemcpy2D, cudaMemcpyToArray, cudaMemcpy2DToArray, cudaMemcpyFromArray, cudaMemcpy2DFromArray, cudaMemcpyArrayToArray, cudaMemcpy2DArrayToArray, cudaMemcpyToSymbol, cudaMemcpyFromSymbol, cudaMemcpyAsync, cudaMemcpy2DAsync, cudaMemcpyToArrayAsync, cudaMemcpy2DToArrayAsync, cudaMemcpy2DFromArrayAsync, cudaMemcpyToSymbolAsync, cudaMemcpyFromSymbolAsync 4.8.2.29 cudaError_t cudaMemcpyFromSymbol (void ∗ dst, const char ∗ symbol, size_t count, size_t offset, enum cudaMemcpyKind kind) Copies count bytes from the memory area pointed to by offset bytes from the start of symbol symbol to the memory area pointed to by dst. The memory areas may not overlap. symbol can either be a variable that resides in global or constant memory space, or it can be a character string, naming a variable that resides in global or constant memory space. kind can be either cudaMemcpyDeviceToHost or cudaMemcpyDeviceToDevice. Parameters: dst - Destination memory address symbol - Symbol source from device count - Size in bytes to copy offset - Offset from start of symbol in bytes kind - Type of transfer Returns: Note: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidSymbol, cudaErrorInvalidDevicePointer, cudaErrorInvalidMemcpyDirection See also: Note that this function may also return error codes from previous, asynchronous launches. cudaMemcpy, cudaMemcpy2D, cudaMemcpyToArray, cudaMemcpy2DToArray, cudaMemcpyFromArray, cudaMemcpy2DFromArray, cudaMemcpyArrayToArray, cudaMemcpy2DArrayToArray, cudaMemcpyToSymbol, cudaMemcpyAsync, cudaMemcpy2DAsync, cudaMemcpyToArrayAsync, cudaMemcpy2DToArrayAsync, cudaMemcpyFromArrayAsync, cudaMemcpy2DFromArrayAsync, cudaMemcpyToSymbolAsync, cudaMemcpyFromSymbolAsync Generated for NVIDIA CUDA Library by Doxygen
4.8 Memory Management 51 4.8.2.30 cudaError_t cudaMemcpyFromSymbolAsync (void ∗ dst, const char ∗ symbol, size_t count, size_t offset, enum cudaMemcpyKind kind, cudaStream_t stream) Copies count bytes from the memory area pointed to by offset bytes from the start of symbol symbol to the memory area pointed to by dst. The memory areas may not overlap. symbol can either be a variable that resides in global or constant memory space, or it can be a character string, naming a variable that resides in global or constant memory space. kind can be either cudaMemcpyDeviceToHost or cudaMemcpyDeviceToDevice. cudaMemcpyFromSymbolAsync() is asynchronous with respect to the host, so the call may return before the copy is complete. It only works on page-locked host memory and returns an error if a pointer to pageable memory is passed as input. The copy can optionally be associated to a stream by passing a non-zero stream argument. If kind is cudaMemcpyDeviceToHost and stream is non-zero, the copy may overlap with operations in other streams. IMPORTANT NOTE: Copies with kind == cudaMemcpyDeviceToDevice are asynchronous with respect to the host, but never overlap with kernel execution. Parameters: dst - Destination memory address symbol - Symbol source from device count - Size in bytes to copy offset - Offset from start of symbol in bytes kind - Type of transfer stream - Stream identifier Returns: Note: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidSymbol, cudaErrorInvalidDevicePointer, cudaErrorInvalidMemcpyDirection See also: Note that this function may also return error codes from previous, asynchronous launches. cudaMemcpy, cudaMemcpy2D, cudaMemcpyToArray, cudaMemcpy2DToArray, cudaMemcpyFromArray, cudaMemcpy2DFromArray, cudaMemcpyArrayToArray, cudaMemcpy2DArrayToArray, cudaMemcpyToSymbol, cudaMemcpyFromSymbol, cudaMemcpyAsync, cudaMemcpy2DAsync, cudaMemcpyToArrayAsync, cudaMemcpy2DToArrayAsync, cudaMemcpyFromArrayAsync, cudaMemcpy2DFromArrayAsync, cudaMemcpy- ToSymbolAsync 4.8.2.31 cudaError_t cudaMemcpyToArray (struct cudaArray ∗ dst, size_t wOffset, size_t hOffset, const void ∗ src, size_t count, enum cudaMemcpyKind kind) Copies count bytes from the memory area pointed to by src to the CUDA array dst starting at the upper left corner (wOffset, hOffset), where kind is one of cudaMemcpyHostToHost, cudaMemcpyHostToDevice, cudaMemcpy- DeviceToHost, or cudaMemcpyDeviceToDevice, and specifies the direction of the copy. Parameters: dst - Destination memory address wOffset - Destination starting X offset hOffset - Destination starting Y offset Generated for NVIDIA CUDA Library by Doxygen
