voidopen(constchar**szName***,intnMode=ios::out,intnProt=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.
