How to wrap C structs in Cython for use in Python? -


For some learning experiences, I'm trying to wrap some parts of SDL (1.2.14) into Cython Python An extension for 3.2

I am having trouble directly converting strontact directly into Python, which is able to directly access its attributes like: 

  struct_name. For example, I want to get struct SDL_Surface:  
  typed text SDL_Rect {Uint32 flags SDL_PixelFormat * format int w, h Uint16 pitch void * pixels SDL_chint clip_ect ER refcount} SDL_Rect;   
 and be able to use it in Python:  
  import SDL # to start the luggage screen = SDL.SetVideoMode (320, 480, 32, SDL .DOUBLEBUF) To access SDL_Surface.w and SDL_Surface.h print (screen.W, '', screen .h), now, I have wrapped the SDL_SetVideoMode and SDL_Surface in a way called a SDL HP file  
  cdf extern from 'sdl.h': # other stuff std SDL_Surface: unsigned long flags SDL_PixelFormat * format int w, h # like the previous declaration ... SDL_Surface * SDL_SetVideoMode (int, int , Int, inti Gned) cdef class Surface: # def Set video mode (width, height, BPP, flags) How to apply: cdef SDL_Surface * screen = SDL_SetVideoMode if the screen is not: err = SDL_GetError () Exception increment (error) # Return Possible way? ... Return page (screen)   
 How should I use SDL? Surface? In a simple case, if the structure is opaque, it is as simple:  
 
 Foo.h "from cdef extern: struct spam: pass   
 When you want to reach members, there are several options, well presented in docs:

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
