| 466 | * A PyArg_ParseTuple "converter" function |
| 467 | * that handles filesystem paths in the manner |
| 468 | * preferred by the os module. |
| 469 | * |
| 470 | * path_converter accepts (Unicode) strings and their |
| 471 | * subclasses, and bytes and their subclasses. What |
| 472 | * it does with the argument depends on the platform: |
| 473 | * |
| 474 | * * On Windows, if we get a (Unicode) string we |
| 475 | * extract the wchar_t * and return it; if we get |
| 476 | * bytes we extract the char * and return that. |
| 477 | * |
| 478 | * * On all other platforms, strings are encoded |
| 479 | * to bytes using PyUnicode_FSConverter, then we |
| 480 | * extract the char * from the bytes object and |
| 481 | * return that. |
| 482 | * |
| 483 | * path_converter also optionally accepts signed |
| 484 | * integers (representing open file descriptors) instead |
| 485 | * of path strings. |
| 486 | * |
| 487 | * Input fields: |
| 488 | * path.nullable |
| 489 | * If nonzero, the path is permitted to be None. |
| 490 | * path.allow_fd |
| 491 | * If nonzero, the path is permitted to be a file handle |
| 492 | * (a signed int) instead of a string. |
| 493 | * path.function_name |
| 494 | * If non-NULL, path_converter will use that as the name |
| 495 | * of the function in error messages. |
| 496 | * (If path.argument_name is NULL it omits the function name.) |
| 497 | * path.argument_name |
| 498 | * If non-NULL, path_converter will use that as the name |
| 499 | * of the parameter in error messages. |
| 500 | * (If path.argument_name is NULL it uses "path".) |
| 501 | * |
| 502 | * Output fields: |
| 503 | * path.wide |
| 504 | * Points to the path if it was expressed as Unicode |
| 505 | * and was not encoded. (Only used on Windows.) |
| 506 | * path.narrow |
| 507 | * Points to the path if it was expressed as bytes, |
| 508 | * or it was Unicode and was encoded to bytes. |
| 509 | * path.fd |
| 510 | * Contains a file descriptor if path.accept_fd was true |
| 511 | * and the caller provided a signed integer instead of any |
| 512 | * sort of string. |
| 513 | * |
| 514 | * WARNING: if your "path" parameter is optional, and is |
| 515 | * unspecified, path_converter will never get called. |
| 516 | * So if you set allow_fd, you *MUST* initialize path.fd = -1 |
| 517 | * yourself! |
| 518 | * path.length |
| 519 | * The length of the path in characters, if specified as |
| 520 | * a string. |
| 521 | * path.object |
| 522 | * The original object passed in. |
| 523 | * path.cleanup |
| 524 | * For internal use only. May point to a temporary object. |
| 525 | * (Pay no attention to the man behind the curtain.) |
| 526 | * |
| 527 | * At most one of path.wide or path.narrow will be non-NULL. |
| 528 | * If path was None and path.nullable was set, |
| 529 | * or if path was an integer and path.allow_fd was set, |
| 530 | * both path.wide and path.narrow will be NULL |
| 531 | * and path.length will be 0. |

Larry Hastings | 9cf065c | 2012-06-22 16:30:09 -0700 | [diff] [blame] | 533 | * path_converter takes care to not write to the path_t |
| 534 | * unless it's successful. However it must reset the |
| 535 | * "cleanup" field each time it's called. |
| 536 | * |
| 537 | * Use as follows: |
| 538 | * path_t path; |
| 539 | * memset(&path, 0, sizeof(path)); |
| 540 | * PyArg_ParseTuple(args, "O&", path_converter, &path); |

| 544 | * (Note that if PyArg_Parse fails you don't need to call |
| 545 | * path_cleanup(). However it is safe to do so.) |
