8. cc(l)
The C compiler supports flexnames. Programs that have symbol
names longer than eight characters are not truncated automatically as
was done with the pre-flexname compiler, which was available in
Version 2.0 and 3.0.
A new option, • T, is provided to truncate long symbol names to eight
characters. This is useful so that new object files can be linked with
older (pre-flexname) files and then run under either old or new
systems.
9. cu(l)
On single phone line systems where the Phone Manager has been
installed, make sure the line is selected to DATA 1 before the cu
command is used.
10. cut(l)
The cut(l) command returns a value of 2 whether or not execution
was successful.
11. diai(3C)
The calling program for the diai(3C) function must include a
statement which defines a static termio structure and assigns its
address to the attr element of the CALL structure. This is necessary
because a NULL value for the attr element in CALL cannot be
passed to the dial function even though the manual page says that a
NULL value for this pointer element may be passed. The problem is
that attr is a pointer to a termio structure that has been defined as an
auto variable, hence it does not get initialized. The structure should
have been declared as static for the variable to default initially to
zero.
On compiling the calling program, the user will see that the dial(3C)
function references the functions tgetent, tgetstr, and tgetnum which
are NOT in libc.a. In order to resolve this, the user should invoke the
compiler as:
$cc prog .c -lc -Itermcap
(note: -lc and -Itermcap must be in this order.)
