example code to draw _any_ exported object?

Hi,

i use 2.41 on Linux and i am known to OpenGL, but not to the file formats used for export.

I search for example code and/or a C library to draw an exported object in OpenGL.

Can anybody suggest a format and has code available to either read such a file or better import it in own C code?

I’d like to use objects that consist of meshes and have color/texture.

Thanks for any hints,
Torsten.
