1870 * - the return value is the number of characters written in the buffer,
1871 * except if the buffer was too small in which case len-2 is returned
1873 * Win2000:
1874 * - if the buffer is 0, 1 or 2 characters long then it is filled with

1876 * - otherwise if the buffer is too small then the first section name that
1877 * does not fit is truncated so that the string list can be terminated

1879 * - the return value is the number of characters written in the buffer
1880 * except for the trailing '\0'. If the buffer is too small, then the
1881 * return value is len-2
1882 * - Win2000 has a bug that triggers when the section names and the
1883 * trailing '\0' fit exactly in the buffer. In that case the trailing
1884 * '\0' is missing.
1886 * Wine implements the observed Win2000 behavior (except for the bug).
