Compute the Bessel function of the second kind for n and
x.
The result of the Bessel function of n and x.

If an error occurs, these functions return 0, but this is also a valid
mathematical result.
If you want to check for errors, set
errno
to 0, call the function, and then check errno again.
These functions don't change errno if no errors occurred. |
