wint_t btowc(
        wint_t c );

PARAMETERS

Points to a variable containing a single-byte character.  

DESCRIPTION

The btowc() function determines if a single-byte value constitutes a valid character in the initial shift state from a multibyte codeset. If so, the function returns the corresponding wide-character value. This function provides a multibyte-character to wide-character format conversion correctly sized for the %c conversion specifier that is permitted in calls to *printf() functions. In general, use either the mbtowc() or mbrtowc() function to perform multibyte-character to wide-character format conversions of single characters.  

RETURN VALUES

The btowc() function returns one of the following: The counterpart wide-character value, if c contains a valid multibyte character in the initial shift state WEOF, if c contains EOF or does not constitute a valid character in the initial shift state from a multibyte codeset  

ERRORS

The btowc() function sets errno to the values specified for the following conditions: An invalid character value was encountered.
