1541 * the first section name then a single '\0' will be returned.
1542 * - the return value is the number of characters written in the buffer,
1543 * except if the buffer was too small in which case len-2 is returned
1544 *
1545 * Win2000:
1546 * - if the buffer is 0, 1 or 2 characters long then it is filled with
1547 * '\0' and the return value is 0
1548 * - otherwise if the buffer is too small then the first section name that
1549 * does not fit is truncated so that the string list can be terminated
1550 * correctly (double '\0')
1551 * - the return value is the number of characters written in the buffer
1552 * except for the trailing '\0'. If the buffer is too small, then the
1553 * return value is len-2
1554 * - Win2000 has a bug that triggers when the section names and the
1555 * trailing '\0' fit exactly in the buffer. In that case the trailing
1556 * '\0' is missing.
1557 *
1558 * Wine implements the observed Win2000 behavior (except for the bug).
