NAME
btowc -- convert a single byte character to a wide character LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <wchar.h> wint_t btowc(int c); DESCRIPTION
The btowc() function converts a single byte character c in the initial shift state of the current locale to a corresponding wide character. The behaviour of btowc() is affected by the LC_CTYPE category of the current locale. RETURN VALUES
The btowc() function returns: WEOF If c is EOF or if (unsigned char) c does not correspond to a valid single byte character representation. (otherwise) A wide character corresponding to c. ERRORS
No errors are defined. SEE ALSO
mbrtowc(3), setlocale(3), wctob(3) STANDARDS
The btowc() function conforms to ISO/IEC 9899/AMD1:1995 (``ISO C90, Amendment 1''). BSD

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 ini- tial 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. SEE ALSO
mbrtowc(3), multibyte(3), wcrtomb(3) STANDARDS
The btowc() and wctob() functions conform to IEEE Std 1003.1-2001 (``POSIX.1''). HISTORY
The btowc() and wctob() functions first appeared in FreeBSD 5.0. BSD
