lt_dlerror() returns NULL?

[Wayne Stewart]

Hi,

It seems to me that either the documentation is wrong, or the function
is.  I don't see any way that 'lt_dlerror()' can return NULL.

  - Function: const char * lt_dlerror (void)
      Return a human readable string describing the most recent error
      that occurred from any of libltdl's functions.  Return `NULL' if
      no errors have occurred since initialization or since it was last
      called.


    const char *
    lt_dlerror ()
    {
      const char *error;

      LT_DLMUTEX_GETERROR (error);
      LT_DLMUTEX_SETERROR (0);

      return error ? error : LT_DLSTRERROR (UNKNOWN);
    }
