Clear or Disable NetBIOS name caches

Question

I am working with Netbios via C++ code (Windows Netbios API).
I did not find that Netbios API have clear cache function.
In order to clear cache i use the "command line" and run:

nbtstat -R

1. Is there a way via code to clear netbious cache ? without opening a console (via code..) and do it ?

2. Is there a way in Operation system to permanently disable Netbios cache ?
