# std::fwide

From cppreference.com
< cpp‎ | io‎ | c

Defined in header `<cwchar>` |  |
int fwide( std::FILE* stream, int mode ); |  |

If `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.

### [edit] Parameters

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

### [edit] Return value

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.
