DESCRIPTION    [Toc]    [Back]

     The btowc() function converts a single-byte character into a corresponding
 wide character.  If the character is EOF or not valid in the initial

     The wctob() function converts a wide character into a corresponding single-byte
 character.  If the wide character is WEOF or not able to be represented
 as a single byte in the initial shift state, wctob() returns
     WEOF.
