btowc — convert single byte to wide character
#include <wchar.h>
wint_t btowc( |
int | c) ; |
The btowc
() function
converts c
,
interpreted as a multibyte sequence of length 1, starting in
the initial shift state, to a wide character and returns it.
If c
is EOF or not a
valid multibyte sequence of length 1, the btowc
() function returns WEOF.
The btowc
() function returns
the wide character converted from the single byte c
. If c
is EOF or not a valid
multibyte sequence of length 1, it returns WEOF.
The behaviour of btowc
()
depends on the LC_CTYPE category of the current locale.
This function should never be used. It does not work for
encodings which have state, and unnecessarily treats single
bytes differently from multibyte sequences. Use the function
mbtowc
() instead.
