#### Description <!-- Describe your changes in detail --> - remove a variable creation Put two variable accessible to the entire function, renaming one to have some clarity. Remove the useless variable.
- Change from using snprintf to memset (no more \0 at last position) This fix possible a memory overflow while using `snprintf`. This also add a \0 at the end of the structure, so a more direct approach with `memset` was used.
