Thanks, but if I try without default values
function create_data(API::Ptr{None}, family, geometry, mode, par::Ptr{
Culonglong},
wesn::Ptr{Cdouble}, inc::Ptr{Cdouble}, reg, pad, data::Ptr{None})
I still get the same error, and note that the Culonglong was not using the
C_NULL default value before. It's the 'dim' parameter below.
using GMT; API=create_session(); dim=uint64([2,9]);
julia> V = create_data (API, 5, 1, 0, dim, C_NULL, C_NULL, 0, 0, C_NULL)
ERROR: no method create_data(Ptr{None}, Int64, Int64, Int64, Array{Uint64,1
}, Ptr{None}, Ptr{None}, Int64, Int64, Ptr{None})
