### Current Pattern ###
cdef class CClass:
  cdef c_struct *c_ptr

  cdef c(self, c_struct *c_ptr):
    self.c_ptr = c_ptr
    # Do stuff
  
  cdef un_c(self):
    # Free resource

def main():
  cdef c_struct the_struct
  c_class = CClass()
  c_class.c(&the_struct)

# -----------------------
### Static Method ###

cdef class CClass:
  cdef c_struct *c_ptr

  def __cinit__(self):
    self.c_ptr = NULL
    # Initialize other resources
  
  def __dealloc__(self):
    # Free resources
  
  @staticmethod
  cdef from_ptr(c_struct *c_ptr):
    cdef CClass c_class = CClass()
    c_class.c_ptr = c_ptr
    return c_class
  
  cdef close(self):
    # Free reosurces
 
# -----------------------
### C-like Pattern ###

cdef class CClass:
  cdef c_struct *c_ptr

  def __cinit__(self):
    self.c_ptr = NULL

  def __dealloc__(self):
    # Free resources

cdef c_class_create(c_struct *c_ptr):
    cdef CClass c_class = CClass()
    c_class.c_ptr = c_ptr
    return c_class

cdef c_class_destroy(CClass c_class):
  # Free resources
