How can I drop packets?

[Matin]

I am running a FreeBSD box as a router on a test network. For my
tests, I have to drop random packets and observe the effects.

What features in C will allow me to drop or preferably delay a packet
before the router forwards the packet?

None at all. The C language has no facilities for
network programming. You'll need a third party library
or perhaps your implementation might provide library
extensions for this.
