missing enums

[prashant-saxena]

Hello,
I am wrapping webgpu library using pyclibrary. You can download the binary depending on your OS from here
The two header files I am processing are webgpu.h and wgpu.h. You can also use the shared library (wgpu_native.dll or wgpu_native.so) from the package.

Here is my initial code:

    parser = CParser(['webgpu.h','wgpu.h'])
    clib = CLibrary('wgpu_native.dll', parser, prefix=['WGPU', 'wgpu'],
                     lock_calls=False, convention='cdll', backend='ctypes')

You will find many enums inside webgpu.h. One of them is this:

typedef enum WGPUTextureUsage {
    WGPUTextureUsage_None = 0x00000000,
    WGPUTextureUsage_CopySrc = 0x00000001,
    WGPUTextureUsage_CopyDst = 0x00000002,
    WGPUTextureUsage_TextureBinding = 0x00000004,
    WGPUTextureUsage_StorageBinding = 0x00000008,
    WGPUTextureUsage_RenderAttachment = 0x00000010,
    WGPUTextureUsage_Force32 = 0x7FFFFFFF
} WGPUTextureUsage;

Correct way to access the members of this enum

clib.TextureUsage.TextureUsage_RenderAttachment
or
clib.TextureUsage.TextureUsage_CopyDst

WGPU and wgpu are gone as prefix, which is required and correct behavior.

The problem is that I'm getting an error:

AttributeError: type object 'c_long' has no attribute 'TextureUsage_RenderAttachment'

clib.TextureUsage is c_long type. Am I missing something here? Although I am not sure about other enums in the headers but I believe the situation would be the same. Another issue #69 is also related to these header and shared library.

Cheers
