580 | ||
581 | C<my_perl> points to the Perl interpreter. It must have been previously | |
582 | created through the use of L</perl_alloc> and L</perl_construct>. It may | |
583 | have been initialised through L</perl_parse>, and may have been used | |
584 | through L</perl_run> and other means. This function should be called for | |
585 | any Perl interpreter that has been constructed with L</perl_construct>, | |
586 | even if subsequent operations on it failed, for example if L</perl_parse> | |
587 | returned a non-zero value. | |
588 | ||
589 | If the interpreter's C<PL_exit_flags> word has the | |
590 | C<PERL_EXIT_DESTRUCT_END> flag set, then this function will execute code | |
591 | in C<END> blocks before performing the rest of destruction. If it is | |
592 | desired to make any use of the interpreter between L</perl_parse> and | |
593 | L</perl_destruct> other than just calling L</perl_run>, then this flag | |
594 | should be set early on. This matters if L</perl_run> will not be called, | |
595 | or if anything else will be done in addition to calling L</perl_run>. | |
596 | ||
597 | Returns a value be a suitable value to pass to the C library function | |
598 | C<exit> (or to return from C<main>), to serve as an exit code indicating | |
599 | the nature of the way the interpreter terminated. This takes into account | |
600 | any failure of L</perl_parse> and any early exit from L</perl_run>. | |
601 | The exit code is of the type required by the host operating system, | |
602 | so because of differing exit code conventions it is not portable to | |
603 | interpret specific numeric values as having specific meanings. | |

1583 | |
1584 | Tells a Perl interpreter to parse a Perl script. This performs most | |
1585 | of the initialisation of a Perl interpreter. See L<perlembed> for | |
1586 | a tutorial. | |
1587 | ||
1588 | C<my_perl> points to the Perl interpreter that is to parse the script. | |
1589 | It must have been previously created through the use of L</perl_alloc> | |
1590 | and L</perl_construct>. C<xsinit> points to a callback function that | |
1591 | will be called to set up the ability for this Perl interpreter to load | |
1592 | XS extensions, or may be null to perform no such setup. | |
1593 | ||
1594 | C<argc> and C<argv> supply a set of command-line arguments to the Perl | |
1595 | interpreter, as would normally be passed to the C<main> function of | |
1596 | a C program. C<argv[argc]> must be null. These arguments are where | |
1597 | the script to parse is specified, either by naming a script file or by | |
1598 | providing a script in a C<-e> option. | |
a3e261d5 Z |
1599 | If L<C<$0>|perlvar/$0> will be written to in the Perl interpreter, then |
1600 | the argument strings must be in writable memory, and so mustn't just be | |
1601 | string constants. | |
0301e899 Z |
1602 | |
1603 | C<env> specifies a set of environment variables that will be used by | |
1604 | this Perl interpreter. If non-null, it must point to a null-terminated | |
1605 | array of environment strings. If null, the Perl interpreter will use | |
1606 | the environment supplied by the C<environ> global variable. | |
1607 | ||
1608 | This function initialises the interpreter, and parses and compiles the | |
1609 | script specified by the command-line arguments. This includes executing | |
1610 | code in C<BEGIN>, C<UNITCHECK>, and C<CHECK> blocks. It does not execute | |
1611 | C<INIT> blocks or the main program. | |
1612 | ||
1613 | Returns an integer of slightly tricky interpretation. The correct | |
1614 | use of the return value is as a truth value indicating whether there | |
1615 | was a failure in initialisation. If zero is returned, this indicates | |
1616 | that initialisation was successful, and it is safe to proceed to call | |
1617 | L</perl_run> and make other use of it. If a non-zero value is returned, | |
1618 | this indicates some problem that means the interpreter wants to terminate. | |
1619 | The interpreter should not be just abandoned upon such failure; the caller | |
1620 | should proceed to shut the interpreter down cleanly with L</perl_destruct> | |
1621 | and free it with L</perl_free>. | |
1622 | ||
1623 | For historical reasons, the non-zero return value also attempts to | |
1624 | be a suitable value to pass to the C library function C<exit> (or to | |
1625 | return from C<main>), to serve as an exit code indicating the nature | |
1626 | of the way initialisation terminated. However, this isn't portable, | |
625e8b0b TC |
1627 | due to differing exit code conventions. A historical bug is preserved |
1628 | for the time being: if the Perl built-in C<exit> is called during this | |
1629 | function's execution, with a type of exit entailing a zero exit code | |
1630 | under the host operating system's conventions, then this function | |
1631 | returns zero rather than a non-zero value. This bug, [perl #2754], | |
1632 | leads to C<perl_run> being called (and therefore C<INIT> blocks and the | |
1633 | main program running) despite a call to C<exit>. It has been preserved | |
1634 | because a popular module-installing module has come to rely on it and | |
1635 | needs time to be fixed. This issue is [perl #132577], and the original | |
1636 | bug is due to be fixed in Perl 5.30. | |

2567 | |
2568 | Tells a Perl interpreter to run its main program. See L<perlembed> | |
2569 | for a tutorial. | |
2570 | ||
2571 | C<my_perl> points to the Perl interpreter. It must have been previously | |
2572 | created through the use of L</perl_alloc> and L</perl_construct>, and | |
2573 | initialised through L</perl_parse>. This function should not be called | |
2574 | if L</perl_parse> returned a non-zero value, indicating a failure in | |
2575 | initialisation or compilation. | |
2576 | ||
2577 | This function executes code in C<INIT> blocks, and then executes the | |
2578 | main program. The code to be executed is that established by the prior | |
2579 | call to L</perl_parse>. If the interpreter's C<PL_exit_flags> word | |
2580 | does not have the C<PERL_EXIT_DESTRUCT_END> flag set, then this function | |
2581 | will also execute code in C<END> blocks. If it is desired to make any | |
2582 | further use of the interpreter after calling this function, then C<END> | |
2583 | blocks should be postponed to L</perl_destruct> time by setting that flag. | |
2584 | ||
2585 | Returns an integer of slightly tricky interpretation. The correct use | |
2586 | of the return value is as a truth value indicating whether the program | |
2587 | terminated non-locally. If zero is returned, this indicates that | |
2588 | the program ran to completion, and it is safe to make other use of the | |
2589 | interpreter (provided that the C<PERL_EXIT_DESTRUCT_END> flag was set as | |
2590 | described above). If a non-zero value is returned, this indicates that | |
2591 | the interpreter wants to terminate early. The interpreter should not be | |
2592 | just abandoned because of this desire to terminate; the caller should | |
2593 | proceed to shut the interpreter down cleanly with L</perl_destruct> | |
2594 | and free it with L</perl_free>. | |
2595 | ||
2596 | For historical reasons, the non-zero return value also attempts to | |
2597 | be a suitable value to pass to the C library function C<exit> (or to | |
2598 | return from C<main>), to serve as an exit code indicating the nature of | |
2599 | the way the program terminated. However, this isn't portable, due to | |
2600 | differing exit code conventions. An attempt is made to return an exit | |
2601 | code of the type required by the host operating system, but because | |
2602 | it is constrained to be non-zero, it is not necessarily possible to | |
2603 | indicate every type of exit. It is only reliable on Unix, where a zero | |
2604 | exit code can be augmented with a set bit that will be ignored. In any | |
2605 | case, this function is not the correct place to acquire an exit code: | |
2606 | one should get that from L</perl_destruct>. | |
