MIO libpcap source initializers.
Most applications should use the interface in mio_config.h to access these initializers.
#define mio_pcap | ( | _s_ | ) | ((pcap_t *)(_s_)->vsp) |
Convenience macro to get a source's currently open pcap context.
Only valid if the source's vsp_type is MIO_T_PCAP.
typedef struct _MIOSourcePCapFileConfig MIOSourcePCapFileConfig |
libpcap dumpfile source configuration context.
Pass as the cfg argument to any pcap file source initializer.
typedef struct _MIOSourcePCapLiveConfig MIOSourcePCapLiveConfig |
libpcap live source configuration context.
Pass as the cfg argument to mio_source_init_pcap_live().
gboolean mio_source_init_pcap_dir | ( | MIOSource * | source, |
const char * | spec, | ||
MIOType | vsp_type, | ||
void * | cfg, | ||
GError ** | err | ||
) |
Initialize a pcap source for reading every libpcap dumpfile from a specified directory.
source | pointer to MIOSource to initialize. This MIOSource will be overwritten. |
spec | input specifier to initialize MIOSource with. Must be the pathname of an accessible directory. |
vsp_type | requested source pointer type, or MIO_T_ANY for default. |
cfg | pointer to configuration context. Must be a pointer to an MIOSourcePcapFileConfig structure. |
err | An error description pointer. |
gboolean mio_source_init_pcap_glob | ( | MIOSource * | source, |
const char * | spec, | ||
MIOType | vsp_type, | ||
void * | cfg, | ||
GError ** | err | ||
) |
Initialize a pcap source for reading every libpcap dumpfile from a specified glob(3) expression.
Fails over to mio_source_init_pcap_single() if the specifier contains no glob expression characters.
source | pointer to MIOSource to initialize. This MIOSource will be overwritten. |
spec | input specifier to initialize MIOSource with. Must be a glob expression. |
vsp_type | requested source pointer type, or MIO_T_ANY for default. |
cfg | pointer to configuration context. Must be a pointer to an MIOSourcePcapFileConfig structure. |
err | An error description pointer. |
gboolean mio_source_init_pcap_live | ( | MIOSource * | source, |
const char * | spec, | ||
MIOType | vsp_type, | ||
void * | cfg, | ||
GError ** | err | ||
) |
Initialize a pcap source for live capture from an interface using libpcap.
Depending on the operating system and configuration, this may require special privileges.
source | pointer to MIOSource to initialize. This MIOSource will be overwritten. |
spec | input specifier to initialize MIOSource with. Must be a valid libpcap interface name. |
vsp_type | requested source pointer type, or MIO_T_ANY for default. |
cfg | pointer to configuration context. Must be a pointer to an MIOSourcePcapLiveConfig structure. |
err | An error description pointer. |
gboolean mio_source_init_pcap_single | ( | MIOSource * | source, |
const char * | spec, | ||
MIOType | vsp_type, | ||
void * | cfg, | ||
GError ** | err | ||
) |
Initialize a pcap source for a single libpcap dumpfile.
Fails over to mio_source_init_pcap_stdin() if specifier is the special string "-".
source | pointer to MIOSource to initialize. This MIOSource will be overwritten. |
spec | input specifier to initialize MIOSource with. Must be a filename. |
vsp_type | requested source pointer type, or MIO_T_ANY for default. |
cfg | pointer to configuration context. Must be a pointer to an MIOSourcePcapFileConfig structure. |
err | An error description pointer. |
gboolean mio_source_init_pcap_stdin | ( | MIOSource * | source, |
const char * | spec, | ||
MIOType | vsp_type, | ||
void * | cfg, | ||
GError ** | err | ||
) |
Initialize a pcap source for a single libpcap dumpfile read from standard input.
source | pointer to MIOSource to initialize. This MIOSource will be overwritten. |
spec | input specifier to initialize MIOSource with. Must be the string "-". |
vsp_type | requested source pointer type, or MIO_T_ANY for default. |
cfg | pointer to configuration context. Must be a pointer to an MIOSourcePcapFileConfig structure. |
err | An error description pointer. |
