for a complicated linux application,
we need to configure ethernet port a lot,
e.g. bring up the port, for 2 ways,
1. system("ifconfig eth0 ... up")
2. write a c function
which way is better ? any concerns for method 1 ? |

1. it's much slower than using system calls directly.
2. difficult to know if execution was done just as the way intended. |

RHEL/CentOS之流才是Linux界的耻辱

But generally you do not want to invoking shell command in your
c code, unless it is quick and dirty solution.
