**Function pointers, variable argument functions calling other variable-argument functions (sort of)**Hi
I have been searching the web and comp.lang.c of a method of using
variable-argument function pointers and the like. And some of the
questions arising in this post are answered partly in these posts, but
I ask mainly for a way to found a way to solve this problem. I'm a
hobbyist so there might be an alltogether better solution to the
problem, so please come with any solution you might think of. I'm open
to ideas. --- And i'm not bound by C. Suggestions from C++ are
welcome.

**Variable argument function as a parameter of a variable argument function**Hi everyone,
I've done a little searching, but I can't quite find an answer to my
question. Everything I've found is more related to how to construct a
variable argument function, and that's not my question.
Suppose I have a variable argument function. Is it possible to use it
to initialize a parameter of another variable argument function?
For example, printf("%s", varArgFcnReturningAString(a,b,c));
I ask because I'm not sure if this is supported by the standard and/or
could be compiler specific.
Thank you for any help, tips, and suggestions!

**Variable variables in function**Everything works fine if I don't use this as a function and just place it
inside my code. When I use it as a function it will return the variables
that are in the "else" portion, but not the if statement. I can see the
variables and echo them inside the function, but not outside of it, but just
on the "if" portion, the "else" part is working fine.
I must be missing something here, any help would be appreciated!

**Put variables into member variables or function variables?**I modify my code into following sample code.
CTest is a class only constructed once when the device power on.
CTest::ExecuteRunState is a function entered periodically.
Do you think whether it is necessary to put the local variables into
class private members?
Otherwise, each time entering the ExecuteRunState(), those local
variables will be decleared and initionalized one time. It's a waste
of cpu resource.

**how do I create nested functions, or functions of functions of a variable**I want to use Scilab to solve a function (E(n,t)) of two separate
functions (n(T) and t(T)), which are both functions of the variable T.
T will range from 122 to 300 in integer values [I would also like to
know how to do this or create a list of scalars which can be inputted
for T]. The "——————" means divided by.
Notice that I must use the constant "e" and powers. I'd appreciate any
help. If you could send a sample of code as well, that would probably
help. Thanks in advance.

**Calling a function that expects variable arguments from a function with variable arguments**I am writing a dynamically growing string buffer. The following struct

**conversion of function of 2 variable to a function of 1 variable?**Hi,
I have Matlab 6.5 and need to have sth like this:
1) m.file - in the working folder
function y=f(x,y);
y=x*y^2+y+1;
2)now the code
root=zeros(n)
n=100;
for s=n:-1:1
h(y)=f(s,y) - here i need your advice (1)
root(s)=fzero(h,0)
end
So my problem is that in fzero h should be a function only of y. How
the command line (1) should be written in matlab language to get
this. I friend of mine told me that in Matlab 7 there is a good
function handle so the line can become h=@(y)(f(s,y)). But in version
6.5 I am not allowed to specify the veriable of interest after @. How
to overcome this. Please, ...

**undefined function or variable #8**Dear all,
I am new to matlab and got stuck with a problem---- undefined function or variable b.
could any of you help me with it? thank you very much.
my function is as follows;
function [ p ] = RT( a )
%UNTITLED2 1-dimension rapid transformation
% Detailed explanation goes here
[m,n]=size(a);
if n~=1
for i=1:n/2
b(i) = a(i) | a(i+n/2);
c(i) = xor(a(i),~a(i+n/2));
end
b=RT(b); c=RT(c);
end
p = [b,c];
end
I have a feeling that the problem may be that b=RT(b) is not correct,but I am not sure and have no idea how to fix it. thank you again!
