int	packetBufferSize

Detailed Description

A struct that contains user configurable parameters for opening a device. All parameters have default values so the user isn't expected to set all parameters or understand exactly how they work

Constructor & Destructor Documentation

◆ DeviceConfiguration()

pcpp::PcapLiveDevice::DeviceConfiguration::DeviceConfiguration	(	DeviceMode	mode = `Promiscuous`,
		int	packetBufferTimeoutMs = `0`,
		int	packetBufferSize = `0`
	)

inline

A c'tor for this struct

Parameters

[in]	mode	The mode to open the device: promiscuous or non-promiscuous. Default value is promiscuous
[in]	packetBufferTimeoutMs	Buffer timeout in millisecond. Default value is 0 which means set timeout of 1 or -1 (depends on the platform)
[in]	packetBufferSize	The packet buffer size. Default value is 0 which means use the default value (varies between different OS's)

Member Data Documentation

◆ mode

DeviceMode pcpp::PcapLiveDevice::DeviceConfiguration::mode

Indicates whether to open the device in promiscuous or normal mode

◆ packetBufferSize

int pcpp::PcapLiveDevice::DeviceConfiguration::packetBufferSize

Set the packet buffer size. You can read more about the packet buffer here: https://www.tcpdump.org/manpages/pcap.3pcap.html . Any value of 100 or above is considered valid, otherwise the default value is used (which varies between different OS's). However, please notice that setting values which are too low or two high may result in failure to open the device. These too low or too high thresholds may vary between OS's, as an example please refer to this thread: https://stackoverflow.com/questions/11397367/issue-in-pcap-set-buffer-size

◆ packetBufferTimeoutMs

int pcpp::PcapLiveDevice::DeviceConfiguration::packetBufferTimeoutMs

Set the packet buffer timeout in milliseconds. You can read more here: https://www.tcpdump.org/manpages/pcap.3pcap.html . Any value above 0 is considered legal, otherwise a value of 1 or -1 is used (depends on the platform)
