### btowc -- Convert Single Byte to Wide Character

Format

>     #include <stdio.h>
>     #include <wchar.h>
>     int btowc(wint_t c);

Language Level: ANSI 93
btowc determines whether c constitutes a valid (one-byte) multibyte character in the initial shift state.

Return Value
If c has the value EOF, or if (unsigned char) c does not constitute a valid (one-byte) multibyte character in the initial shift state, btowc returns WEOF.

Otherwise, btowc returns the wide-character representation of that character.
