1473 | ** The following routines are provided to make life easier when | |
1474 | ** converting among VMS-style and Unix-style directory specifications. | |
1475 | ** All will take input specifications in either VMS or Unix syntax. On | |
1476 | ** failure, all return NULL. If successful, the routines listed below | |
748a9306 | 1477 | ** return a pointer to a buffer containing the appropriately |
a0d0e21e LW |
1478 | ** reformatted spec (and, therefore, subsequent calls to that routine |
1479 | ** will clobber the result), while the routines of the same names with | |
1480 | ** a _ts suffix appended will return a pointer to a mallocd string | |
1481 | ** containing the appropriately reformatted spec. | |
1482 | ** In all cases, only explicit syntax is altered; no check is made that | |
1483 | ** the resulting string is valid or that the directory in question | |
1484 | ** actually exists. | |
1485 | ** | |
1486 | ** fileify_dirspec() - convert a directory spec into the name of the | |
1487 | ** directory file (i.e. what you can stat() to see if it's a dir). | |
1488 | ** The style (VMS or Unix) of the result is the same as the style | |
1489 | ** of the parameter passed in. | |
1490 | ** pathify_dirspec() - convert a directory spec into a path (i.e. | |
1491 | ** what you prepend to a filename to indicate what directory it's in). | |
1492 | ** The style (VMS or Unix) of the result is the same as the style | |
1493 | ** of the parameter passed in. | |
1494 | ** tounixpath() - convert a directory spec into a Unix-style path. | |
1495 | ** tovmspath() - convert a directory spec into a VMS-style path. | |
1496 | ** tounixspec() - convert any file spec into a Unix-style file spec. | |
1497 | ** tovmsspec() - convert any file spec into a VMS-style spec. | |

3374 | * call out the the regular perl routines in doio.c which do an | |
3375 | * execvp (for those who really want to try this under VMS). | |
3376 | * Otherwise, they do exactly what the perl docs say exec should | |
3377 | * do - terminate the current script and invoke a new command | |
3378 | * (See below for notes on command syntax.) | |
3379 | * | |
3380 | * do_aspawn() and do_spawn() implement the VMS side of the perl | |
3381 | * 'system' function. | |
3382 | * | |
3383 | * Note on command arguments to perl 'exec' and 'system': When handled | |
3384 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |
3385 | * are concatenated to form a DCL command string. If the first arg | |
3386 | * begins with '$' (i.e. the perl script had "\$ Type" or some such), | |
3eeba6fb | 3387 | * the the command string is handed off to DCL directly. Otherwise, |
a0d0e21e LW |
3388 | * the first token of the command is taken as the filespec of an image |
3389 | * to run. The filespec is expanded using a default type of '.EXE' and | |
3eeba6fb | 3390 | * the process defaults for device, directory, etc., and if found, the resultant |
a0d0e21e | 3391 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
3eeba6fb | 3392 | * the command string as parameters. This is perhaps a bit complicated, |
a0d0e21e LW |
3393 | * but I hope it will form a happy medium between what VMS folks expect |
3394 | * from lib$spawn and what Unix folks expect from exec. | |
