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 behaviour of this function is affected by the LC_CTYPE category of the current locale.

 RETURN VALUE

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 representation of that character.
