libretro \- library to fit version 7 programs on version 6 systems
\fBcc \-I/usr/include/retrofit ... -lretro -lS
These implement version 7 functions on version 6 systems.
returns just the real user id; the high 8 bits are thus normally clear.
perform the normal operations, but rearrange the expand tabs bit into
``tab3'' delay as version 7 does.
maps a version 6 stat into the version 7 structure.
``HOME'' to return the home directory of the real user, or
``TERM'' to return a string giving the terminal type in use.
It returns 0 for everything else.
tells whether the specified unit is attaches to a terminal.
so it will work separate i/d.
This library also defines ``_ctype'' as in stdio, but fixed so that
end-of-file (\-1) has the correct attributes (as it does in version 7),
/usr/include/retrofit root for header files
/etc/htmp data base for \fIgetenv\fR
