typedef basic_fstream<wchar_t> wfstream;
File stream (wide)

Input/output stream class to operate on files using wide characters.

This is an instantiation of basic_fstream with the following template parameters:

Apart from the internal file buffer of type wfilebuf, objects of this class keep a set of internal fields inherited from ios_base, wios and wistream:

fieldmember functionsdescription
Formattingformat flagsflags
A set of internal flags that affect how certain input/output operations are interpreted or generated.
See member type fmtflags.
field widthwidthWidth of the next formatted element to insert.
display precisionprecisionDecimal precision for the next floating-point value inserted.
The locale object used by the function for formatted input/output operations affected by localization properties.
fill characterfillCharacter to pad a formatted field up to the field width (width).
Stateerror staterdstate
The current error state of the stream.
Individual values may be obtained by calling good, eof, fail and bad.
See member type iostate.
exception maskexceptionsThe state flags for which a failure exception is thrown.
See member type iostate.
Othercallback stackregister_callbackStack of pointers to functions that are called when certain events occur.
extensible arraysiword
Internal arrays to store objects of type long and void*.
tied streamtiePointer to output stream that is flushed before each i/o operation on this stream.
stream bufferrdbufPointer to the associated basic_streambuf object, which is charge of all input/output operations.
character countgcountCount of characters read by last unformatted input operation (input streams only).
