Defined in header <wchar.h>
wint_t btowc( int c );		(since C95)

Widens a single-byte character c (reinterpreted as unsigned char) to its wide character equivalent.

Most multibyte character encodings use single-byte codes to represent the characters from the ASCII character set. This function may be used to convert such characters to wchar_t.

Parameters

c

-

single-byte character to widen

Return value

WEOF if c is EOF

wide character representation of c if (unsigned char)c is a valid single-byte character in the initial shift state, WEOF otherwise.
