I am looking for a programm!

Does anybody knows where I could find a programm in C,which could construct a buffer, with input and output floating numbers and then to be able to destroy the buffer?
if anybody has information about such a programm, I would be gratefull

A buffer with input and output? I think you mean you have a buffer which contains elements of type float or double. You want to create it dynamically and destroy it. Am I correct?

Declare a ptr to the buffer:

double *buffer;

Create the buffer:

buffer = malloc (buffersize);

Destroy the buffer:

free (buffer);
