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 is 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:
- The
symbol paramater may also be a character string, naming a variable that resides in global or constant memory space, however this usage is deprecated as of CUDA 4.1.
Note that this function may also return error codes from previous, asynchronous launches.
This function exhibits synchronous behavior for most use cases.
