Constructor & Destructor Documentation

CConsoleRedirector()

mrpt::system::CConsoleRedirector::CConsoleRedirector ( const std::string &  out_file, bool  also_to_console = true, bool  also_cerr = true, bool  append_file = false, int  bufferSize = 1000  )

inline

Constructor.

Parameters

out_file	The file to create / append
also_to_console	Whether to redirect data to file and also dump data to the console as usual.
append_file	If set to false the file will be truncated on open
bufferSize	It's recommended to buffer the data instead of writing characters one by one.
also_cerr	Whether to redirect the output to std::cerr in addition to std::cout.

Exceptions

std::exception

If the file cannot be opened.
