There is a topic:

However could some one give an example how to pass 3-d or 4-d array to C
function.
I have Array{Float64, 4} and for ccall I use Ptr{Ptr{Ptr{Ptr{Float64 as
Type of parameter. Is there some way to make it m

Is there way to pass Dictionary from Julia to C function using ccall???
I have to divide all dictionaries for subarrays and then send them to C...
this is really long and leads to huge syntax. Is there way to pass whole
dictionary at once?
Thank you
