2019-09-04Load environment vars to globals for efficency.Anders Broman1-1/+1
These environment variables are read very frequently, read them once to globals for performance improvment.

2018-09-30Fix the type of the packet buffer argument to a capture dissector.Guy Harris1-2/+2
It's a blob of bytes, so the right type is guint8 *, not guchar *. (Yes, in practice, they're both typedefs for "unsigned char" - sadly, C's data types didn't make a distinction between "byte-sized integral value" and "character" - but given that we have different names, let's use them to make it clearer what's being done.)

Kept backwards compatibility with GTK+ capture info dialog by keeping the protocols tracked hardcoded, but Qt should have more freedom.

While it currently only contains packet_counts, it will hopefully stabilize the capture function signature if more fields are added.

2015-12-14Create capture dissector tables.Michael Mann1-13/+58
They are modeled after dissection dissector tables, but for the moment, don't have/need the flexibility. They are intended to be much simpler/faster than full dissection. The two most used/needed are "wtap_encap" and "ethertype", so they were the basis of starting to use and test capture dissector table API. Others may be added in the future. The "capture dissector" function signature needed a bit of tweeking to handling "claiming" of a packet. The current application of this is capture functions returning TRUE if they affected a "type" of packet count. Returning FALSE ends up considering the packet an "other" type.

2015-12-13Create a way to register "capture" dissectors.Michael Mann1-0/+85
Capture dissectors could be architected like dissection dissectors, with tables and subtables and possibly using tvbs to pass there data instead of raw byte arrays. This is a first step towards that by refactoring capture_info_packet() to work off of a "capture dissector table" Registering the capture dissection functions instead of calling them directly also clears up a bunch of dissector header files who sole purpose was providing the capture dissection function definition.
