Status Checking Functions

All of the descriptor manipulation, FFT computation, and descriptor configuration functions return an integer value denoting the status of the operation. The functions in this category check that status. The first function is a logical function that checks whether the status reflects an error of a predefined class, and the second is an error message function that returns a character string.
