NAME
       libnvme_set_test_base_dir - Reroot libnvme's on-disk files for testing

SYNOPSIS
       int libnvme_set_test_base_dir (struct libnvme_global_ctx *ctx , const
       char *path );

ARGUMENTS
       ctx         struct libnvme_global_ctx object

       path        Sandbox directory under /tmp, or NULL to restore defaults

DESCRIPTION
       Redirects the files libnvme reads and writes (the exclusion list, the
       ownership registry, ...) under path instead of their production
       locations, so a test can run against a throwaway directory.  For safety
       path must be confined to /tmp and contain no ".." component; anything
       else is rejected.  Passing NULL clears a previously set override.

RETURN
       0 on success, -EINVAL if ctx is NULL or path is not a valid sandbox
       path, -ENOMEM on allocation failure.
