Function getrf 

pub unsafe fn getrf(
    handle: &Handle,
    m: i32,
    n: i32,
    array_d_a: *mut *mut c_void,
    ia: i32,
    ja: i32,
    desc_a: &MatrixDesc,
    array_d_ipiv: *mut *mut c_int,
    compute_type: cudaDataType,
    array_d_work: *mut *mut c_void,
    lwork: i64,
    info: &mut [c_int],
) -> Result<()>

Safety

Same pointer-array requirements as getrf_buffer_size.
