Member Data Documentation

◆ buffer_size

int interface_options_tag::buffer_size

Capture buffer size in megabytes requested from the kernel.

◆ cfilter

char* interface_options_tag::cfilter

Capture filter string applied to this interface.

◆ descr

char* interface_options_tag::descr

User-friendly description of the interface; may be NULL if unavailable.

◆ display_name

char* interface_options_tag::display_name

Name displayed in the console and title bar.

◆ extcap

char* interface_options_tag::extcap

Path to the extcap executable for this interface; NULL if not an extcap interface.

◆ extcap_args

GHashTable* interface_options_tag::extcap_args

Key-value argument table passed to the extcap executable.

◆ extcap_control_in

char* interface_options_tag::extcap_control_in

Path to the extcap control input FIFO.

◆ extcap_control_out

char* interface_options_tag::extcap_control_out

Path to the extcap control output FIFO.

◆ extcap_fifo

char* interface_options_tag::extcap_fifo

Path to the FIFO or pipe used to receive data from the extcap process.

◆ extcap_pid

GPid interface_options_tag::extcap_pid

PID of the running extcap process, or WS_INVALID_PID if not running.

◆ extcap_pipedata

void* interface_options_tag::extcap_pipedata

Internal state for reading data from the extcap pipe.

◆ extcap_stderr

GString* interface_options_tag::extcap_stderr

Accumulated stderr output from the extcap process.

◆ extcap_stderr_watch

unsigned interface_options_tag::extcap_stderr_watch

GLib I/O watch ID for the extcap stderr pipe.

◆ extcap_stdout_watch

unsigned interface_options_tag::extcap_stdout_watch

GLib I/O watch ID for the extcap stdout pipe.

◆ hardware

char* interface_options_tag::hardware

Description of the interface hardware.

◆ has_snaplen

bool interface_options_tag::has_snaplen

Whether a snapshot length limit is set.

◆ if_type

interface_type interface_options_tag::if_type

Interface type classification (e.g. standard, pipe, extcap).

◆ ifname

char* interface_options_tag::ifname

If non-NULL, overrides the interface name written into Interface Description Blocks (IDBs).

◆ linktype

int interface_options_tag::linktype

Selected link-layer type (DLT) for this capture session.

◆ monitor_mode

bool interface_options_tag::monitor_mode

Whether monitor mode (rfmon) is requested for this interface.

◆ name

char* interface_options_tag::name

Interface name supplied to libpcap/WinPcap/Npcap to identify the interface.

◆ optimize

int interface_options_tag::optimize

Whether the capture filter is compiled with optimization enabled: 1 = yes, 0 = no.

◆ promisc_mode

bool interface_options_tag::promisc_mode

Whether promiscuous mode is requested.

◆ snaplen

int interface_options_tag::snaplen

Snapshot length in bytes; only meaningful if has_snaplen is true.

◆ timestamp_type

char* interface_options_tag::timestamp_type

Requested timestamp type as a string; NULL if using the default.

◆ timestamp_type_id

int interface_options_tag::timestamp_type_id

Numeric timestamp type passed to pcap_set_tstamp_type(); valid only when timestamp_type is non-NULL.
