3339 | * | |
3340 | * vms_do_aexec() and vms_do_exec() are called in response to the | |
3341 | * perl 'exec' function. If this follows a vfork call, then they | |
3342 | * call out the the regular perl routines in doio.c which do an | |
3343 | * execvp (for those who really want to try this under VMS). | |
3344 | * Otherwise, they do exactly what the perl docs say exec should | |
3345 | * do - terminate the current script and invoke a new command | |
3346 | * (See below for notes on command syntax.) | |
3347 | * | |
3348 | * do_aspawn() and do_spawn() implement the VMS side of the perl | |
3349 | * 'system' function. | |
3350 | * | |
3351 | * Note on command arguments to perl 'exec' and 'system': When handled | |
3352 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |
3353 | * are concatenated to form a DCL command string. If the first arg | |
3354 | * begins with '$' (i.e. the perl script had "\$ Type" or some such), | |
3eeba6fb | 3355 | * the the command string is handed off to DCL directly. Otherwise, |
a0d0e21e LW |
3356 | * the first token of the command is taken as the filespec of an image |
3357 | * to run. The filespec is expanded using a default type of '.EXE' and | |
3eeba6fb | 3358 | * the process defaults for device, directory, etc., and if found, the resultant |
a0d0e21e | 3359 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
3eeba6fb | 3360 | * the command string as parameters. This is perhaps a bit complicated, |
a0d0e21e LW |
3361 | * but I hope it will form a happy medium between what VMS folks expect |
3362 | * from lib$spawn and what Unix folks expect from exec. | |

3741 | * Here are replacements for the following Unix routines in the VMS environment: | |
3742 | * getpwuid Get information for a particular UIC or UID | |
3743 | * getpwnam Get information for a named user | |
3744 | * getpwent Get information for each user in the rights database | |
3745 | * setpwent Reset search to the start of the rights database | |
3746 | * endpwent Finish searching for users in the rights database | |
3747 | * | |
3748 | * getpwuid, getpwnam, and getpwent return a pointer to the passwd structure | |
3749 | * (defined in pwd.h), which contains the following fields:- | |
3750 | * struct passwd { | |
3751 | * char *pw_name; Username (in lower case) | |
3752 | * char *pw_passwd; Hashed password | |
3753 | * unsigned int pw_uid; UIC | |
3754 | * unsigned int pw_gid; UIC group number | |
3755 | * char *pw_unixdir; Default device/directory (VMS-style) | |
3756 | * char *pw_gecos; Owner name | |
3757 | * char *pw_dir; Default device/directory (Unix-style) | |
3758 | * char *pw_shell; Default CLI name (eg. DCL) | |
3759 | * }; | |
3760 | * If the specified user does not exist, getpwuid and getpwnam return NULL. | |
3761 | * | |
3762 | * pw_uid is the full UIC (eg. what's returned by stat() in st_uid). | |
3763 | * not the UIC member number (eg. what's returned by getuid()), | |
3764 | * getpwuid() can accept either as input (if uid is specified, the caller's | |
3765 | * UIC group is used), though it won't recognise gid=0. | |
3766 | * | |
3767 | * Note that in VMS it is necessary to have GRPPRV or SYSPRV to return | |
3768 | * information about other users in your group or in other groups, respectively. | |
3769 | * If the required privilege is not available, then these routines fill only | |
3770 | * the pw_name, pw_uid, and pw_gid fields (the others point to an empty | |
3771 | * string). | |
