cudaError_t cudaMemcpyFromSymbol ( void *  dst, const char *  symbol, size_t  count, size_t  offset = 0, enum cudaMemcpyKind  kind = cudaMemcpyDeviceToHost   ) 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: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidSymbol, cudaErrorInvalidDevicePointer, cudaErrorInvalidMemcpyDirection Note: Note that this function may also return error codes from previous, asynchronous launches.
