1311 | * The section names are returned as a list of strings with an extra |
1312 | * '\0' to mark the end of the list. Except for that the behavior |
1313 | * depends on the Windows version. |
1314 | * |
1315 | * Win95: |
1316 | * - if the buffer is 0 or 1 character long then it is as if it was of |
1317 | * infinite length. |
1318 | * - otherwise, if the buffer is to small only the section names that fit |
1319 | * are returned. |
1320 | * - note that this means if the buffer was to small to return even just |
1321 | * the first section name then a single '\0' will be returned. |
1322 | * - the return value is the number of characters written in the buffer, |
1323 | * except if the buffer was too smal in which case len-2 is returned |
1324 | * |
1325 | * Win2000: |
1326 | * - if the buffer is 0, 1 or 2 characters long then it is filled with |
1327 | * '\0' and the return value is 0 |
1328 | * - otherwise if the buffer is too small then the first section name that |
1329 | * does not fit is truncated so that the string list can be terminated |
1330 | * correctly (double '\0') |
1331 | * - the return value is the number of characters written in the buffer |
1332 | * except for the trailing '\0'. If the buffer is too small, then the |
1333 | * return value is len-2 |
1334 | * - Win2000 has a bug that triggers when the section names and the |
1335 | * trailing '\0' fit exactly in the buffer. In that case the trailing |
1336 | * '\0' is missing. |
1337 | * |
1338 | * Wine implements the observed Win2000 behavior (except for the bug). |
1339 | * |
1340 | * Note that when the buffer is big enough then the return value may be any |
1341 | * value between 1 and len-1 (or len in Win95), including len-2. |
