509 | =head1 DESCRIPTION |
| 510 | |
| fe2e802c |
511 | The C<warnings> pragma is a replacement for the command line flag C<-w>, |
| 512 | but the pragma is limited to the enclosing block, while the flag is global. |
| 513 | See L<perllexwarn> for more information. |
| 514 | |
| 0453d815 |
515 | If no import list is supplied, all possible warnings are either enabled |
| 516 | or disabled. |
| 599cee73 |
517 | |
| 0ca4541c |
518 | A number of functions are provided to assist module authors. |

| 523 | |
| 7e6d00f8 |
524 | Creates a new warnings category with the same name as the package where |
| 525 | the call to the pragma is used. |
| 526 | |
| 527 | =item warnings::enabled() |
| 528 | |
| 529 | Use the warnings category with the same name as the current package. |
| 530 | |
| 531 | Return TRUE if that warnings category is enabled in the calling module. |
| 532 | Otherwise returns FALSE. |
| 533 | |
| 534 | =item warnings::enabled($category) |
| 535 | |
| 536 | Return TRUE if the warnings category, C<$category>, is enabled in the |
| 537 | calling module. |
| 538 | Otherwise returns FALSE. |
| 539 | |
| 540 | =item warnings::enabled($object) |
| 541 | |
| 542 | Use the name of the class for the object reference, C<$object>, as the |
| 543 | warnings category. |
| 544 | |
| 545 | Return TRUE if that warnings category is enabled in the first scope |
| 546 | where the object is used. |
| 547 | Otherwise returns FALSE. |
| 548 | |
| 549 | =item warnings::warn($message) |
| 550 | |
| 551 | Print C<$message> to STDERR. |
| 552 | |
| 553 | Use the warnings category with the same name as the current package. |
| 554 | |
| 555 | If that warnings category has been set to "FATAL" in the calling module |
| 556 | then die. Otherwise return. |
| 557 | |
| 558 | =item warnings::warn($category, $message) |
| 559 | |
| 560 | Print C<$message> to STDERR. |
| 561 | |
| 562 | If the warnings category, C<$category>, has been set to "FATAL" in the |
| 563 | calling module then die. Otherwise return. |

567 | Print C<$message> to STDERR. |
| e476b1b5 |
568 | |
| 7e6d00f8 |
569 | Use the name of the class for the object reference, C<$object>, as the |
| 570 | warnings category. |
| e476b1b5 |
571 | |
| 7e6d00f8 |
572 | If that warnings category has been set to "FATAL" in the scope where C<$object> |
| 573 | is first used then die. Otherwise return. |
