1560  *
1561  * Returns the section names contained in the specified file.
1562  * FIXME: Where do we find this file when the path is relative?
1563  * The section names are returned as a list of strings with an extra
1564  * '\0' to mark the end of the list. Except for that the behavior
1565  * depends on the Windows version.
1566  *
1567  * Win95:
1568  * - if the buffer is 0 or 1 character long then it is as if it was of
1569  *   infinite length.
1570  * - otherwise, if the buffer is too small only the section names that fit
1571  *   are returned.
1572  * - note that this means if the buffer was too small to return even just
1573  *   the first section name then a single '\0' will be returned.
1574  * - the return value is the number of characters written in the buffer,
1575  *   except if the buffer was too small in which case len-2 is returned
1576  *
1577  * Win2000:
1578  * - if the buffer is 0, 1 or 2 characters long then it is filled with
1579  *   '\0' and the return value is 0
1580  * - otherwise if the buffer is too small then the first section name that
1581  *   does not fit is truncated so that the string list can be terminated
1582  *   correctly (double '\0')
1583  * - the return value is the number of characters written in the buffer
1584  *   except for the trailing '\0'. If the buffer is too small, then the
1585  *   return value is len-2
1586  * - Win2000 has a bug that triggers when the section names and the
1587  *   trailing '\0' fit exactly in the buffer. In that case the trailing
1588  *   '\0' is missing.
1589  *
1590  * Wine implements the observed Win2000 behavior (except for the bug).
1591  *
1592  * Note that when the buffer is big enough then the return value may be any
1593  * value between 1 and len-1 (or len in Win95), including len-2.
