fwide
(FILE
*stream, int
mode);
fwide
() function determines the orientation of the
stream pointed at by stream.
If the orientation of stream has already
been determined, fwide
() leaves it unchanged.
Otherwise, fwide
() sets the orientation of
stream according to mode.
If mode is less than zero, stream is set to byte-oriented. If it is greater than zero, stream is set to wide-oriented. Otherwise, mode is zero, and stream is unchanged.
fwide
() returns a value according to orientation after
the call of fwide
(); a value less than zero if
byte-oriented, a value greater than zero if wide-oriented, and zero if the
stream has no orientation.
fwide
() function conforms to
ISO/IEC 9899:1999 (“ISO C99”).
