These functions let the UI enumerate the available interfaces.
|
|
|
|
First, rawnet_enumadapter_open() is used to start enumeration.
|
|
|
|
rawnet_enumadapter() is then used to gather information for each adapter present
|
|
on the system, where:
|
|
|
|
ppname points to a pointer which will hold the name of the interface
|
|
ppdescription points to a pointer which will hold the description of the interface
|
|
|
|
For each of these parameters, new memory is allocated, so it has to be
|
|
freed with lib_free().
|
|
Note: The description can be NULL, since pcap_if_t.desc can be NULL, so
|
|
check the description before calling lib_free() on it.
|
|
|
|
rawnet_enumadapter_close() must be used to stop processing.
|
|
|
|
Each function returns 1 on success, and 0 on failure.
|
|
rawnet_enumadapter() only fails if there is no more adpater; in this case,
|
|
*ppname and *ppdescription are not altered.
