| 892 | ** return a pointer to a buffer containing the appropriately |
| 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. |

| 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. |

| 2929 | * Here are replacements for the following Unix routines in the VMS environment: |
| 2930 | * getpwuid Get information for a particular UIC or UID |
| 2931 | * getpwnam Get information for a named user |
| 2932 | * getpwent Get information for each user in the rights database |
| 2933 | * setpwent Reset search to the start of the rights database |
| 2934 | * endpwent Finish searching for users in the rights database |
| 2935 | * |
| 2936 | * getpwuid, getpwnam, and getpwent return a pointer to the passwd structure |
| 2937 | * (defined in pwd.h), which contains the following fields:- |
| 2938 | * struct passwd { |
| 2939 | * char *pw_name; Username (in lower case) |
| 2940 | * char *pw_passwd; Hashed password |
| 2941 | * unsigned int pw_uid; UIC |
| 2942 | * unsigned int pw_gid; UIC group number |
| 2943 | * char *pw_unixdir; Default device/directory (VMS-style) |
| 2944 | * char *pw_gecos; Owner name |
| 2945 | * char *pw_dir; Default device/directory (Unix-style) |
| 2946 | * char *pw_shell; Default CLI name (eg. DCL) |
| 2947 | * }; |
| 2948 | * If the specified user does not exist, getpwuid and getpwnam return NULL. |
| 2949 | * |
| 2950 | * pw_uid is the full UIC (eg. what's returned by stat() in st_uid). |
| 2951 | * not the UIC member number (eg. what's returned by getuid()), |
| 2952 | * getpwuid() can accept either as input (if uid is specified, the caller's |
| 2953 | * UIC group is used), though it won't recognise gid=0. |
| 2954 | * |
| 2955 | * Note that in VMS it is necessary to have GRPPRV or SYSPRV to return |
| 2956 | * information about other users in your group or in other groups, respectively. |
| 2957 | * If the required privilege is not available, then these routines fill only |
| 2958 | * the pw_name, pw_uid, and pw_gid fields (the others point to an empty |
| 2959 | * string). |
