qhullptr([err_file=C_NULL])

Allocate a pointer to a Qhull data structure. This will allocate memory that must be freed with qhullfree when work with the pointer is complete.

qhullptr(f::Function, args...; kwargs...)

Apply the function f to the result of qhullptr(args...; kwargs...) and free the resulting memory. Please use this auto-freeing form unless there is a specific scenario that requires manual memory management.
