Still doesn't work but getting closer
julia> using GMT; API=create_session(); dim=uint64([2,9]);
julia> V = create_data (API, 5, 1, 0)
Ptr{Void} @0x0000000000000000
julia> V = create_data (API, 5, 1, 0, dim)
ERROR: no method create_data(Ptr{None}, Int64, Int64, Int64, Array{Uint64,1
})
so its the 'dim' parameter that is causing the error now. Isn't the dim=
uint64([2,9]); compatible with par::Ptr=C_NULL (nor the before
par::Ptr{Culonglong})?
