MPE/iX NOTES
The current
MPE/iX implementation of cpio has the following limitations:
• It converts non-byte stream files to byte stream files before archiving them. File charac-
teristics like file code, record size, and so forth are not preserved by this conversion.
When you extract files from an archive, they are written as byte stream files.
• It displays file owner names as 17 character fields in the form username.accountname and
group names as 8 character fields in the form groupname.
• Because this release of MPE/iX does not provide the lstat() API, cpio cannot return
information on the link itself. It attempts to determine when a symbolic link has been ref-
erenced, but can only return the information on the target of the link, rather than the link
itself.
For more information on how the current
MPE/iX implementation may affect the operation of
this utility, see Appendix A, MPE/iX Implementation Considerations.
