Member Function Documentation

void io::Stream::open (  std::string  file_name, std::string  mode, bool  allow_close = true )

Open a stream. If the file name ends with ".gz" a pipe through gzip is created. If the file name ends with "|", an input pipe is created. In that case, the mode must be "r". If the file name starts with "|", an output pipe is created. If the stream was open already, close the previous stream before opening a new one. Parameters: file_name  = the file or pipe to open mode  = the mode for the file. See the man page of fopen() for more details. Possible values are "r", "r+", "w", "w+", "a", "a+", but only "r" and "w" are suppoerted for pipes and gzipped files. allow_close  = should the close() actually close the file
