Defined in header <wchar.h>
int wctob( wint_t c );

Narrows a wide character c if its multibyte character equivalent in the initial shift state is a single byte.

This is typically possible for the characters from the ASCII character set, since most multibyte encodings (such as UTF-8) use single bytes to encode those characters.


[edit] Parameters

c - wide character to narrow

[edit] Return value

EOF if c does not represent a multibyte character with length 1 in initial shift state.

otherwise, the single-byte representation of c as unsigned char converted to int
