Just a thought, but it might be helpful for things like put_dword()
and put_string() to return the offset at which they wrote something,
so that you could instead do something like the following:

ctab_base = put_dword(buffer, sizeof(D3DXSHADER_CONSTANTTABLE));
creator_offset = put_dword(buffer, 0);
...
offset = put_string(buffer, vkd3d_shader_get_version(NULL, NULL));
set_dword(buffer, creator_offset, (offset - ctab_base) * sizeof(*buffer->data));
