void open( const char* szName, int nMode = ios::out, int nProt = filebuf::openprot );
Parameters
szName
The name of the file to be opened during construction.
nMode
An integer containing mode bits defined as ios enumerators that can be combined with the OR ( | ) operator. See the ofstream constructor for a list of the enumerators. The ios::out mode is implied.
nProt
The file protection specification; defaults to the static integer filebuf::openprot. See the ofstream constructor for a list of the other allowed values.
Remarks
Opens a disk file and attaches it to the stream’s filebuf object. If the filebuf object is already attached to an open file, or if a filebuf call fails, the ios::failbit is set. If the file is not found, the ios::failbit is set only if the ios::nocreate mode was used.
