/** Get operating system and architecture information

\verbatim embed:rst
The :cpp:func:`lammps_get_os_info` function can be used to retrieve
detailed information about the hosting operating system and
compiler/runtime.
A suitable buffer for a C-style string has to be provided and its length.
If the assembled text will be truncated to not overflow this buffer.
