Member Function Documentation

void ResolvConfEventHandler::GetDnsAddresses ( const std::string &  resolv_file, AddressList *  addresses  )

static

Returns any nameserver IP addresses from file

Reads a file, line by line. Returns the IP addresses corresponding to nameservers (i.e. from lines "nameserver <IP_ADDRESS>")

Here is the caller graph for this function:

bool ResolvConfEventHandler::Handle ( const std::string &  file_path, file_watcher::Event  event, bool *  clear_handler  )

virtual

Handle function called per event

Parameters

file_path	- the path of the file this event corresponds to
event	- the type of event
clear_handler	- (output) set this to true to have the event handler remove from the loop after this call

Should return false in case of failure.

Setting the clear_handler parameter to false means that the FileWatcher object will attempt to re-register the handler for the same file name in the case a file was delete - useful for continuously watching a file which may be deleted and recreated

Implements file_watcher::EventHandler.
