Neither the C nor C++ languages specify variable attenuators. In engineering, an "attenuator" is something that reduces the amplification of a signal or other source. The closest C or any other programming language would come to such an operation is through the negative "-", divide "/" or bitwise-right ">>" operators.
If this is in reference to a library which interacts with a physical mechanism through C, you will need to refer to the manual for the library's API for further information.

What are functions used for in math?
There are used to encapsulate a relationship between two or more variables.
What is the number of symmetric Boolean functions of n variables and it's proof?
2^(n+1)
HOW to find the product of two probability density functions?
The answer depends on whether or not the two variables are independent.
Why are first-degree functions called linear functions?
In the special case of two related variables (e.g., 2x - 7y + 5 = 0), the graph is a straight line.
What is the use of extern variable?
External Variables are declared outside all functions, yet are available to all functions that care to use them. Features of external variables : Storage : Memory Default Initial value : zero Scope : Global Life : As long as program's execution does't come to an end
