Description
In this call AMGX_RC AMGX_API AMGX_matrix_upload_all(AMGX_matrix_handle mtx, int n, int nnz, int block_dimx, int block_dimy, const int *row_ptrs, const int *col_indices, const void *data, const void *diag_data); the number of nnz is int, and I have a fairly large matrix with nnz larger than the max value of int, how do we solve that issues?

Research direction
Start with the AMGX_matrix_upload_all API declaration in the issue and trace how its nnz argument is represented and consumed. Determine the supported approach for matrices whose nonzero count exceeds the int range, including the API compatibility implications; done means a documented, validated solution for large nnz values.
