    void* A,
    unsigned long long p_bufSize,
    unsigned int offset,
    unsigned int kernelIndex = 0,
    unsigned int deviceIndex = 0

This function copies a matrix in FPGA device memory to host memory by its address in device memory.


A pointer to matrix A in the host memory
p_bufSize size of matrix A
offset A’s address in device 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
