On OpenVMS, the struct _iobuf is needed to access members of the struct
This is a patch for the affected stdioext modules to compile on OpenVMS.
The approach looks generally right, but I'd request a couple of changes
before this can go in:
* Is _IOERR defined on OpenVMS? In some files, you treat OpenVMS
as part of the _IOERR case, in others you do it before _IOERR. Which
is not consistent.
If _IOERR is defined on OpenVMS, please update all
#elif defined _IOERR /* AIX, HP-UX, IRIX, OSF/1, Solaris, OpenServer, mingw, MSVC, NonStop Kernel */
lines to include OpenVMS at the end of the comment.
* Instead of defining a variable 'stream', please using the same coding
style as for the other platforms: use macro fp_ which is defined to
a cast expression through lib/stdio-impl.h.
* The fbufmode.c change has a regression for all non-Windows, non-OpenVMS
* The freading.c change is misindented.
