2343 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args |
2344 | * are concatenated to form a DCL command string. If the first arg |

2346 | * the the command string is hrnded off to DCL directly. Otherwise, |
2347 | * the first token of the command is taken as the filespec of an image |
2348 | * to run. The filespec is expanded using a default type of '.EXE' and |
2349 | * the process defaults for device, directory, etc., and the resultant |
2350 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
2351 | * the command string as parameters. This is perhaps a bit compicated, |

2627 | * If the specified user does not exist, getpwuid and getpwnam return NULL. |
2628 | * |
2629 | * pw_uid is the full UIC (eg. what's returned by stat() in st_uid). |
2630 | * not the UIC member number (eg. what's returned by getuid()), |
2631 | * getpwuid() can accept either as input (if uid is specified, the caller's |
2632 | * UIC group is used), though it won't recognise gid=0. |
2633 | * |
2634 | * Note that in VMS it is necessary to have GRPPRV or SYSPRV to return |
2635 | * information about other users in your group or in other groups, respectively. |
2636 | * If the required privilege is not available, then these routines fill only |
2637 | * the pw_name, pw_uid, and pw_gid fields (the others point to an empty |

3227 | * If it is less than 0, no timestamps are preserved. If it is 0, then |
3228 | * rmscopy() will behave similarly to the DCL COPY command: timestamps are |
3229 | * propagated to the output file at creation iff the output file specification |
3230 | * did not contain an explicit name or type, and the revision date is always |
3231 | * updated at the end of the copy operation. If it is greater than 0, then |
3232 | * it is interpreted as a bitmask, in which bit 0 indicates that timestamps |
3233 | * other than the revision date should be propagated, and bit 1 indicates |
3234 | * that the revision date should be propagated. |
3235 | * |
3236 | * Returns 1 on success; returns 0 and sets errno and vaxc$errno on failure. |
