579 | ||
580 | C<my_perl> points to the Perl interpreter. It must have been previously | |
581 | created through the use of L</perl_alloc> and L</perl_construct>. It may | |
582 | have been initialised through L</perl_parse>, and may have been used | |
583 | through L</perl_run> and other means. This function should be called for | |
584 | any Perl interpreter that has been constructed with L</perl_construct>, | |
585 | even if subsequent operations on it failed, for example if L</perl_parse> | |
586 | returned a non-zero value. | |
587 | ||
588 | If the interpreter's C<PL_exit_flags> word has the | |
589 | C<PERL_EXIT_DESTRUCT_END> flag set, then this function will execute code | |
590 | in C<END> blocks before performing the rest of destruction. If it is | |
591 | desired to make any use of the interpreter between L</perl_parse> and | |
592 | L</perl_destruct> other than just calling L</perl_run>, then this flag | |
593 | should be set early on. This matters if L</perl_run> will not be called, | |
594 | or if anything else will be done in addition to calling L</perl_run>. | |
595 | ||
596 | Returns a value be a suitable value to pass to the C library function | |
597 | C<exit> (or to return from C<main>), to serve as an exit code indicating | |
598 | the nature of the way the interpreter terminated. This takes into account | |
599 | any failure of L</perl_parse> and any early exit from L</perl_run>. | |
600 | The exit code is of the type required by the host operating system, | |
601 | so because of differing exit code conventions it is not portable to | |
602 | interpret specific numeric values as having specific meanings. | |

1568 | ||
1569 | Tells a Perl interpreter to parse a Perl script. This performs most | |
1570 | of the initialisation of a Perl interpreter. See L<perlembed> for | |
1571 | a tutorial. | |
1572 | ||
1573 | C<my_perl> points to the Perl interpreter that is to parse the script. | |
1574 | It must have been previously created through the use of L</perl_alloc> | |
1575 | and L</perl_construct>. C<xsinit> points to a callback function that | |
1576 | will be called to set up the ability for this Perl interpreter to load | |
1577 | XS extensions, or may be null to perform no such setup. | |
1578 | ||
1579 | C<argc> and C<argv> supply a set of command-line arguments to the Perl | |
1580 | interpreter, as would normally be passed to the C<main> function of | |
1581 | a C program. C<argv[argc]> must be null. These arguments are where | |
1582 | the script to parse is specified, either by naming a script file or by | |
1583 | providing a script in a C<-e> option. | |
a3e261d5 Z |
1584 | If L<C<$0>|perlvar/$0> will be written to in the Perl interpreter, then |
1585 | the argument strings must be in writable memory, and so mustn't just be | |
1586 | string constants. | |
0301e899 Z |
1587 | |
1588 | C<env> specifies a set of environment variables that will be used by | |
1589 | this Perl interpreter. If non-null, it must point to a null-terminated | |
1590 | array of environment strings. If null, the Perl interpreter will use | |
1591 | the environment supplied by the C<environ> global variable. | |
1592 | ||
1593 | This function initialises the interpreter, and parses and compiles the | |
1594 | script specified by the command-line arguments. This includes executing | |
1595 | code in C<BEGIN>, C<UNITCHECK>, and C<CHECK> blocks. It does not execute | |
1596 | C<INIT> blocks or the main program. | |
1597 | ||
1598 | Returns an integer of slightly tricky interpretation. The correct | |
1599 | use of the return value is as a truth value indicating whether there | |
1600 | was a failure in initialisation. If zero is returned, this indicates | |
1601 | that initialisation was successful, and it is safe to proceed to call | |
1602 | L</perl_run> and make other use of it. If a non-zero value is returned, | |
1603 | this indicates some problem that means the interpreter wants to terminate. | |
1604 | The interpreter should not be just abandoned upon such failure; the caller | |
1605 | should proceed to shut the interpreter down cleanly with L</perl_destruct> | |
1606 | and free it with L</perl_free>. | |
1607 | ||
1608 | For historical reasons, the non-zero return value also attempts to | |
1609 | be a suitable value to pass to the C library function C<exit> (or to | |
1610 | return from C<main>), to serve as an exit code indicating the nature | |
1611 | of the way initialisation terminated. However, this isn't portable, | |
857320cb Z |
1612 | due to differing exit code conventions. A historical bug is preserved |
1613 | for the time being: if the Perl built-in C<exit> is called during this | |
1614 | function's execution, with a type of exit entailing a zero exit code | |
1615 | under the host operating system's conventions, then this function | |
1616 | returns zero rather than a non-zero value. This bug, [perl #2754], | |
1617 | leads to C<perl_run> being called (and therefore C<INIT> blocks and the | |
1618 | main program running) despite a call to C<exit>. It has been preserved | |
1619 | because a popular module-installing module has come to rely on it and | |
1620 | needs time to be fixed. This issue is [perl #132577], and the original | |
1621 | bug is due to be fixed in Perl 5.30. | |

2549 | ||
2550 | Tells a Perl interpreter to run its main program. See L<perlembed> | |
2551 | for a tutorial. | |
2552 | ||
2553 | C<my_perl> points to the Perl interpreter. It must have been previously | |
2554 | created through the use of L</perl_alloc> and L</perl_construct>, and | |
2555 | initialised through L</perl_parse>. This function should not be called | |
2556 | if L</perl_parse> returned a non-zero value, indicating a failure in | |
2557 | initialisation or compilation. | |
2558 | ||
2559 | This function executes code in C<INIT> blocks, and then executes the | |
2560 | main program. The code to be executed is that established by the prior | |
2561 | call to L</perl_parse>. If the interpreter's C<PL_exit_flags> word | |
2562 | does not have the C<PERL_EXIT_DESTRUCT_END> flag set, then this function | |
2563 | will also execute code in C<END> blocks. If it is desired to make any | |
2564 | further use of the interpreter after calling this function, then C<END> | |
2565 | blocks should be postponed to L</perl_destruct> time by setting that flag. | |
2566 | ||
2567 | Returns an integer of slightly tricky interpretation. The correct use | |
2568 | of the return value is as a truth value indicating whether the program | |
2569 | terminated non-locally. If zero is returned, this indicates that | |
2570 | the program ran to completion, and it is safe to make other use of the | |
2571 | interpreter (provided that the C<PERL_EXIT_DESTRUCT_END> flag was set as | |
2572 | described above). If a non-zero value is returned, this indicates that | |
2573 | the interpreter wants to terminate early. The interpreter should not be | |
2574 | just abandoned because of this desire to terminate; the caller should | |
2575 | proceed to shut the interpreter down cleanly with L</perl_destruct> | |
2576 | and free it with L</perl_free>. | |
2577 | ||
2578 | For historical reasons, the non-zero return value also attempts to | |
2579 | be a suitable value to pass to the C library function C<exit> (or to | |
2580 | return from C<main>), to serve as an exit code indicating the nature of | |
2581 | the way the program terminated. However, this isn't portable, due to | |
2582 | differing exit code conventions. An attempt is made to return an exit | |
2583 | code of the type required by the host operating system, but because | |
2584 | it is constrained to be non-zero, it is not necessarily possible to | |
2585 | indicate every type of exit. It is only reliable on Unix, where a zero | |
2586 | exit code can be augmented with a set bit that will be ignored. In any | |
2587 | case, this function is not the correct place to acquire an exit code: | |
2588 | one should get that from L</perl_destruct>. | |
