852 | ** return a pointer to a buffer containing the appropriately |
a0d0e21e |

854 | ** will clobber the result), while the routines of the same names with |
855 | ** a _ts suffix appended will return a pointer to a mallocd string |
856 | ** containing the appropriately reformatted spec. |
857 | ** In all cases, only explicit syntax is altered; no check is made that |
858 | ** the resulting string is valid or that the directory in question |
859 | ** actually exists. |
860 | ** |
861 | ** fileify_dirspec() - convert a directory spec into the name of the |
862 | ** directory file (i.e. what you can stat() to see if it's a dir). |
863 | ** The style (VMS or Unix) of the result is the same as the style |
864 | ** of the parameter passed in. |
865 | ** pathify_dirspec() - convert a directory spec into a path (i.e. |
866 | ** what you prepend to a filename to indicate what directory it's in). |
867 | ** The style (VMS or Unix) of the result is the same as the style |
868 | ** of the parameter passed in. |
869 | ** tounixpath() - convert a directory spec into a Unix-style path. |
870 | ** tovmspath() - convert a directory spec into a VMS-style path. |
871 | ** tounixspec() - convert any file spec into a Unix-style file spec. |
872 | ** tovmsspec() - convert any file spec into a VMS-style spec. |

2475 | * vms_do_aexec() and vms_do_exec() are called in response to the |
2476 | * perl 'exec' function. If this follows a vfork call, then they |
2477 | * call out the the regular perl routines in doio.c which do an |
2478 | * execvp (for those who really want to try this under VMS). |
2479 | * Otherwise, they do exactly what the perl docs say exec should |
2480 | * do - terminate the current script and invoke a new command |
2481 | * (See below for notes on command syntax.) |
2482 | * |
2483 | * do_aspawn() and do_spawn() implement the VMS side of the perl |
2484 | * 'system' function. |
2485 | * |
2486 | * Note on command arguments to perl 'exec' and 'system': When handled |
2487 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args |
2488 | * are concatenated to form a DCL command string. If the first arg |
2489 | * begins with '$' (i.e. the perl script had "\$ Type" or some such), |
2490 | * the the command string is hrnded off to DCL directly. Otherwise, |
2491 | * the first token of the command is taken as the filespec of an image |
2492 | * to run. The filespec is expanded using a default type of '.EXE' and |
2493 | * the process defaults for device, directory, etc., and the resultant |
2494 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
2495 | * the command string as parameters. This is perhaps a bit compicated, |
2496 | * but I hope it will form a happy medium between what VMS folks expect |
2497 | * from lib$spawn and what Unix folks expect from exec. |

2752 | * Here are replacements for the following Unix routines in the VMS environment: |
2753 | * getpwuid Get information for a particular UIC or UID |
2754 | * getpwnam Get information for a named user |
2755 | * getpwent Get information for each user in the rights database |
2756 | * setpwent Reset search to the start of the rights database |
2757 | * endpwent Finish searching for users in the rights database |
2758 | * |
2759 | * getpwuid, getpwnam, and getpwent return a pointer to the passwd structure |
2760 | * (defined in pwd.h), which contains the following fields:- |
2761 | * struct passwd { |
2762 | * char *pw_name; Username (in lower case) |
2763 | * char *pw_passwd; Hashed password |
2764 | * unsigned int pw_uid; UIC |
2765 | * unsigned int pw_gid; UIC group number |
2766 | * char *pw_unixdir; Default device/directory (VMS-style) |
2767 | * char *pw_gecos; Owner name |
2768 | * char *pw_dir; Default device/directory (Unix-style) |
2769 | * char *pw_shell; Default CLI name (eg. DCL) |
2770 | * }; |
2771 | * If the specified user does not exist, getpwuid and getpwnam return NULL. |
2772 | * |
2773 | * pw_uid is the full UIC (eg. what's returned by stat() in st_uid). |
2774 | * not the UIC member number (eg. what's returned by getuid()), |
2775 | * getpwuid() can accept either as input (if uid is specified, the caller's |
2776 | * UIC group is used), though it won't recognise gid=0. |
2777 | * |
2778 | * Note that in VMS it is necessary to have GRPPRV or SYSPRV to return |
2779 | * information about other users in your group or in other groups, respectively. |
2780 | * If the required privilege is not available, then these routines fill only |
2781 | * the pw_name, pw_uid, and pw_gid fields (the others point to an empty |
2782 | * string). |
