BTOWC(3) FreeBSD Library Functions Manual BTOWC(3)
NAME
btowc, wctob - convert between wide and single-byte characters
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
wint_t
btowc(int c);
int
wctob(wint_t c);
#include <wchar.h>
#include <xlocale.h>
wint_t
btowc_l(int c, locale_t loc);
int
wctob_l(wint_t c, locale_t loc);
DESCRIPTION
The btowc() function converts a single-byte character into a
corresponding wide character. If the character is EOF or not valid in
the initial shift state, btowc() returns WEOF.
The wctob() function converts a wide character into a corresponding
single-byte character. If the wide character is WEOF or not able to be
represented as a single byte in the initial shift state, wctob() returns
EOF.
The _l-suffixed versions take an explicit locale argument, while the non-
suffixed versions use the current global or per-thread locale.
