[libredwg] GauchoCAD + libredwg

[Martin]

Hi.

First of all excuse 'nil' knowledge of C since I have just started trying to use the library with Extern, export or whatever is the correct name of the method.

My name is Martín Belmonte (belmotek) and I am one of the GauchoCAD [1] developers.
I made a module to try to do something with the C library in Gambas[2], but as expected it doesn't work :-(
My goals are the following:
1) Read DWG and DXF files
2) List all entities and their properties
3) Write DWG DXF with these altered properties.

As I am learning I will go step by step.
What functions and structures should I use for, for example, create a list of layers?

Some of Gambas development team can help but we need to know what functions we should use.

Note: Actually I use a lot of code to parse the extracted text file with the dwgread tool in the terminal, but it is not the optimal way I guess.

Thank you very much in advance.

Martín.
