waitbar function error. Pls help

[prads]

Hello,
this waitbar function (similar to the one in matlab) in C++ pops an error. Pls correct the error for me.
Thanks,

DEFUN_DLD(waitb ar, args, nargout,
"waitbar(...);\ n\
WAITBAR displays a text-based wait bar. This function\n\
is similar to the Matlab waitbar command, but it is\n\
a text, rather than graphical function.\n\n\
A typical usage of WAITBAR in a lengthy computation\n\
(inside a FOR loop, for example) is as follows:\n\n\
for i=1:1000\n\
## computation\n\
waitbar(i/1000);\n\
end\n\n\
WAITBAR(X,TITLE ), where 0 <= X <= 1, sets the position of\n\
the waitbar to the fractional length X. Values of X exactly\n\
equal to 0 or 1 clear the waitbar. The optional second\n\
argument TITLE sets the waitbar caption to TITLE.\n\n\
If Octave is running in a smart terminal, the width is\n\
automatically detected, and the title is displayed in the\n\
waitbar (and truncated if it is too long). Otherwise, the\n\
title is not displayed and the width is initialized to a\n\
default of 50 characters, or it can be set to N characters\n\
with WAITBAR(0,N). If no terminal is detected (such as when\n\
Octave is run in batch mode and output is redirected), no\n\
output is generated.\n\n\
For compatibility with the Matlab version of this function\n\
(which is graphical rather than text-based), additional\n\
arguments are ignored, but there are no guarantees of perfect\n\
compatibility." )

What's the error? Compile time or run time?

Also, please use code tage when posting.

I have added them for you this time.

[prads]

It shows the foll errors.....

octave/oct.h: No such file or directory.
39 expected constructor, destructor, or type conversion before '(' token
39 expected `,' or `;' before '(' token

Thanks,
Prads

[prads]

I am sorry........li ne 39 in my code corresponds to 18 in the above code. i.e the error is in DEFUN_DLD()
Thanks,
prads

DEFUN_DLD() is a function?

Then what does the function prototype look like?

I'm having trouble reading the code between line 19 and 44.
