ptr is a pointer to the beginning of an array of structs. Steve has

I have a C function:
int foo(foo_t *handle, int idx, void **ptr);
foo() fills in ptr which points at (part of) an array of elements that was
previously allocated. I want to call this function from Julia.
For a bits type (i.e. Int64), the following works:
p = [C_NULL]
ccall((:foo, libfoo), Cint
