The API looks quite small, so I would suggest to just type it out -- from a
quick look, everything should be wrappable in pure Julia. e.g. the
equivalent to the first part of hello.cpp you linked would be:
julia> immutable BeagleInstanceDetails
resourceNumber::Int
resourceName::Ptr{Cchar}
implName::Ptr{Cchar}
implDescription::Ptr{Cchar}
flags::Clong
end
julia> retInfo = [BeagleInstanceDetails(0,0,0,0,0)]
1-element Array{BeagleInstanceDetails,1}:
BeagleInstanceDetails(0,Ptr{Int8} @0x0000000000000000,Ptr{Int8}
@0x000000000000
0000,Ptr{Int8} @0x0000000000000000,0)
julia> nPatterns=2
2
julia> ccall((:beagleCreateInstance, "hmsbeagle64"), Int,
(Cint,Cint,Cint,Cint,Cint,Cint,Cint,Cint,Cint,Ptr{Int},
Cint,Clong,Clong,Ptr{BeagleInstanceDetails}),
3,2,3,4,nPatterns,1,4,1,0,C_NULL,0,0,0,retInfo)
0
julia> retInfo
1-element Array{BeagleInstanceDetails,1}:
BeagleInstanceDetails(0,Ptr{Int8} @0x0000000002a2d54c,Ptr{Int8}
@0x0000000002a2
f040,Ptr{Int8} @0x00000000003e3390,135320150)
