In reading up on raw socket programming under RedHat 9.2,
I come across 'typedef struct pcap pcap_t' in pcap.h.
Ok, so pcap_t is of type pcap, but I can't find any
include file that tells me what pcap is itself. Ideas,
anyone?

There's no requirement that struct pcap be defined, as long as there is
no attempt to use it's members or take it's size. If you need to find
out what it contains, try asking in a RedHat or Linux forum.

Quite possibly you're not supposed to know. `struct pcap' might
be defined only in the implementation of pcap, with its contents
supposed to be opaque to users.

No, `pcap_t' is of type `struct pcap'.

No, 'pcap_t' is an alias for the type 'struct pcap'. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Take a solution with a project hierarchy along the lines of an n-tier

The presentation layer is coupled to the business layer, and the business

Suppose the data layer raises an event, and it passes Me (the sender) as an

Hi All,
I have a timer, if my data queue Q has data, the timer should start
work, if there is no data in Q, the timer should stop.
However, there is an event can fire timer to start.
Should I add a variable to know how many records inside Q ?
Ya, I think so, because timer should use for unknown events, check it
in a period.

Hi everyone, I am brand new to Java and not really even sure what I'm doing... I'm supposed to be writing a Timer class that is part of a stop watch application, and it seems to me that the program is correct, but when I run the tester, it is obviously not. The goal is to enter a base and a time, and find time % base, then tell how many times it cycled back to zero. I don't know what is wrong with my program, because it appears to me that it...
