mode > 0, attempts to make
stream wide-oriented. If
mode < 0, attempts to make
stream byte-oriented. If mode==0, only queries the current orientation of the stream.
|stream||-||pointer to the C I/O stream to modify or query|
|mode||-||integer value greater than zero to set the stream wide, less than zero to set the stream narrow, or zero to query only|
An integer greater than zero if the stream is wide-oriented after this call, less than zero if the stream is byte-oriented after this call, and zero if the stream has no orientation.
