Constructor & Destructor Documentation

mfem::ofgzstream::ofgzstream	(	char const *	name,
		char const *	mode = default_mode
	)

Simple replacement for class std::ofstream that can transparently create files compressed in gzip format (when mode contains the character 'z') or regular uncompressed files. Internally, the classes std::filebuf or gzstreambuf are used to handle the file I/O. The mode chars are as in gzopen() with additional caveat that presence of a 'z' character indicates desire to compress. Default mode is "zwb6". Writing compressed files requires the MFEM build-time option MFEM_USE_GZSTREAM.

Note

For uncompressed files, the mode option is ignored and the file is opened with std::ios_base::out mode.
