Standard C Library Functions                                         btowc(3C)



NAME
       btowc - single-byte to wide-character conversion

SYNOPSIS
       #include <stdio.h>
       #include <wchar.h>

       wint_t btowc(int c);

DESCRIPTION
       The  btowc()  function  determines  whether c constitutes a valid (one-
       byte) character in the initial shift state.


       The behavior of this function is affected by the LC_CTYPE  category  of
       the current locale. See environ(7).

RETURN VALUES
       The  btowc()  function  returns  WEOF  if  c  has  the  value EOF or if
       (unsigned char)c does not constitute a valid  (one-byte)  character  in
       the  initial shift state. Otherwise, it returns the wide-character rep‐
       resentation of that character.

ERRORS
       No errors are defined.
