xfblasStatus_t xfblasGetByPointer ( void* A, unsigned int kernelIndex = 0, unsigned int deviceIndex = 0 )
This function copies a matrix in the FPGA device memory to the host memory by a pointer.
Parameters:
| A | Pointer to matrix A in the host memory. |
| kernelIndex | Index of kernel that is being used; default is 0. |
| deviceIndex | Index of device that is being used; default is 0. |
| xfblasStatus_t | 0 if the operation completed successfully. |
| xfblasStatus_t | 1 if the library was not initialized. |
| xfblasStatus_t | 3 if there is no FPGA device memory allocated for the matrix. |
