890 | ** All will take input specifications in either VMS or Unix syntax. On | |
891 | ** failure, all return NULL. If successful, the routines listed below | |
748a9306 | 892 | ** return a pointer to a buffer containing the appropriately |
a0d0e21e LW |
893 | ** reformatted spec (and, therefore, subsequent calls to that routine |
894 | ** will clobber the result), while the routines of the same names with | |
895 | ** a _ts suffix appended will return a pointer to a mallocd string | |
896 | ** containing the appropriately reformatted spec. | |
897 | ** In all cases, only explicit syntax is altered; no check is made that | |
898 | ** the resulting string is valid or that the directory in question | |
899 | ** actually exists. | |
900 | ** | |
901 | ** fileify_dirspec() - convert a directory spec into the name of the | |
902 | ** directory file (i.e. what you can stat() to see if it's a dir). | |
903 | ** The style (VMS or Unix) of the result is the same as the style | |
904 | ** of the parameter passed in. | |
905 | ** pathify_dirspec() - convert a directory spec into a path (i.e. | |
906 | ** what you prepend to a filename to indicate what directory it's in). | |
907 | ** The style (VMS or Unix) of the result is the same as the style | |
908 | ** of the parameter passed in. | |
909 | ** tounixpath() - convert a directory spec into a Unix-style path. | |
910 | ** tovmspath() - convert a directory spec into a VMS-style path. | |
911 | ** tounixspec() - convert any file spec into a Unix-style file spec. | |
912 | ** tovmsspec() - convert any file spec into a VMS-style spec. | |

2628 | * my_vfork() - just a vfork(), after setting a flag to record that | |
2629 | * the current script is trying a Unix-style fork/exec. | |
2630 | * | |
2631 | * vms_do_aexec() and vms_do_exec() are called in response to the | |
2632 | * perl 'exec' function. If this follows a vfork call, then they | |
2633 | * call out the the regular perl routines in doio.c which do an | |
2634 | * execvp (for those who really want to try this under VMS). | |
2635 | * Otherwise, they do exactly what the perl docs say exec should | |
2636 | * do - terminate the current script and invoke a new command | |
2637 | * (See below for notes on command syntax.) | |
2638 | * | |
2639 | * do_aspawn() and do_spawn() implement the VMS side of the perl | |
2640 | * 'system' function. | |
2641 | * | |
2642 | * Note on command arguments to perl 'exec' and 'system': When handled | |
2643 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |
2644 | * are concatenated to form a DCL command string. If the first arg | |
2645 | * begins with '$' (i.e. the perl script had "\$ Type" or some such), | |
2646 | * the the command string is hrnded off to DCL directly. Otherwise, | |
2647 | * the first token of the command is taken as the filespec of an image | |
2648 | * to run. The filespec is expanded using a default type of '.EXE' and | |
2649 | * the process defaults for device, directory, etc., and the resultant | |
2650 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of | |
2651 | * the command string as parameters. This is perhaps a bit compicated, | |
2652 | * but I hope it will form a happy medium between what VMS folks expect | |
2653 | * from lib$spawn and what Unix folks expect from exec. | |
