[Pyrex] Assign C object to a cdeffed variable of a class

[Stefano Esposito]

Hi all,

i'm trying to write a python bindings to a library in pyrex (this is my first try in usin pyrex).

I hava a C function declared (in the .h file) as this:

  int alpm_pkg_load (const char *filename, pmpkg_t **pkg);

and which i've declared to pyrex as follows:
  ing alpm_pkg_load (char *filname, pmpkg_t **pkg);

the pmpkg_t is an exter struct and i've declared it as:

  ctypedef struct pmpkg_t

i have defined a class like follows:

  cdef class Package:
     cdef pmpkg_t *pkg
     [...]

what i'd like to do is to call the alpm_pkg_load from a module function like:

  def package_new_from_file (filename):
	cdef pmpkg_t *pkg
	
	alpm_pkg_load (filename, &pkg)

and then assing the pkg variable to the pkg member of Package class. I've tried with simply:

	pypkg = Package()
	pypkg.pkg = pkg

but pyrexc complains to cannot convert pmpkg_t (*) to a Python object. Is there a way to do something similar or a work around?
