Hi!=20 I'm developing some API functions using cbq / tc (for GUI based BW Manage= ment) By two approches i can do this, 1. By excuting cbq.init script (which is executable) using some system ca= lls=20 like execv etc.=09 Are there any problems by doing so? OR=20 2. Directly using iproute2/tc source code with slight modifications. So, Which option is better? Are there any other solutions, please welcome. thanks & regards, Srikanth.=20
