[issue19023] ctypes docs: Unimplemented and undocumented features

[Martin Panter]

Martin Panter added the comment:

Okay I have committed the Array and _Pointer stuff. I suggest if anyone wants 
to work on the Union classes, they open a separate report. (I never understood 
what they are for. C doesn’t have much little or big endian stuff; byte order 
mostly depends on the ABI, so why is ctypes different?)

Posting a new patch, rebased against the recent “default” (3.5) branch:

* Tweaked so that sentences start with a capital letter
* Added _Pointer.contents

[issue19023] ctypes docs: Unimplemented and undocumented features

[Martin Panter]

Martin Panter added the comment:

Here is the patch stripped of all the noise and the structure and union stuff, 
so you can see just the changes related to arrays and pointers. However I have 
not attempted to apply the patch, nor addressed Georg’s comment about the 
“contents” attribute.

Can someone add this in?  What needs to be done to make it happen? Kind of need 
this for a project I'm working on...

[issue19023] ctypes docs: Unimplemented and undocumented features

[Georg Brandl]

Georg Brandl added the comment:

Thanks for the patch! The amount of unrelated changes (mostly removing  
empty prompts) makes this a bit hard to review.

Also, I don't think it is too important to link to the ctypes module from 
within the docs of ctypes :)

Please separate out the implementation of the Union classes into a separate 
patch.

The Array docs look good to me.  The _Pointer docs talk about reading and 
writing the elements using standard subscript and slice accesses.  That is 
true for pointers pointing to arrays, but .contents should be mentioned as 
well.

[issue19023] ctypes docs: Unimplemented and undocumented features

[Sye van der Veen]

New submission from Sye van der Veen:

In the ctypes documentation, there's mention of a 
BigEndianUnion/LittleEndianUnion that isn't actually implemented, and the 
Arrays and pointers section just reads Not yet written.

The attached patch adds the (Big|Little)EndianUnion classes (with tests), 
finishes the Array/_Pointer class docs (and adds missing cases to the tests), 
and makes some stylistic improvements to docs.

The patch was made against default, but it's quite likely it could be 
back-ported all the way to Python 3.1.
