Subj:	Re: C curses

    I recently came across the next problem;

     1070    1       mvgetstr(10, 20, pword);
    %CC-W-TOOMANYMACARGS, Argument list for macro "mvgetstr" contains
                    too many arguments;  excess arguments ignored.
    
    %CC-W-TOOFEWMACARGS, Argument list for macro "mvwgetstr" contains
                    too few arguments;  missing arguments assumed to be null.
    
    %CC-W-IGNORED, Unexpected "," ignored.

    ...

    VAX C bug ??
    
    (VAX C V2.1-007 under VAX VMS V4.5)

A quick look at SYS$LIBRARY:CURSES.H reveals:

# define mvwgetstr(win,y,x,str)	(wmove(win,y,x)==ERR)?ERR:wgetstr(win,str)
# define mvgetstr(y,x)		mvwgetstr (stdscr, y, x)

mvgetstr() has been erroneously defined as taking only two parameters - the
str parameter is missing.  It, in turn, proceeds to call mvwgetstr() without
the str parameter - but mvwgetstr() is defined WITH the str parameter.  Hence,
the error messages you saw.

Congratulations!  You've found a genuine VAX C bug!

You should SPR this.  In the meantime, there's an easy work-around:  Make a
private copy of CURSES.H, correct the error, and use it.  Note:  If you find
that there is no file named SYS$LIBRARY:CURSES.H, your system manager has
installed VAX C using just the text libraries for the system include files.
In that case, to get your own copy of CURSES.H, do:

	$ LIBRARY SYS$LIBRARY:VAXCDEF/TEXT/EXTRACT:CURSES/OUTPUT:CURSES.H

BTW, version 2.2 of VAX C has been out for quite some time - V2.3 is almost
here - so you are dealing with old software.  However, the same problem appears
on my VMS 4.5/VAX C 2.2 system, so the problem MAY still be current.
