Simplify Buffer Handling in Non-Linux Platforms

This change removes unnecessary buffer operations for non-Linux
platforms by directly returning string literals without allocating or
copying into a buffer. On Linux platforms, the buffer (buf) remains
defined and unchanged.

The update ensures consistency while simplifying the code and
eliminating redundant logic.
