Detailed Description

This file keeps all the new definitions and typedefs that are exported to the user and that are needed for the RPCAP protocol.

All the RPCAP functions that are allowed to return a buffer containing the error description can return max PCAP_ERRBUF_SIZE characters. However there is no guarantees that the string will be zero-terminated. Best practice is to define the errbuf variable as a char of size 'PCAP_ERRBUF_SIZE+1' and to insert manually the termination char at the end of the buffer. This will guarantee that no buffer overflows occur even if we use the printf() to show the error on the screen.

This file declares some typedefs that MUST be of a specific size. These definitions (i.e. typedefs) could need to be changed on other platforms than Intel IA32.

This file defines some structures that are used to transfer data on the network. Be careful that you compiler MUST not insert padding into these structures for better alignment. These structures have been created in order to be correctly aligned to a 32 bits boundary, but be careful in any case.
