WCTOMB(3) BSD Library Functions Manual WCTOMB(3) NAME wctomb, wctomb_l -- convert a wide-character code to a character LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <stdlib.h> int wctomb(char *s, wchar_t wchar); #include <stdlib.h> #include <xlocale.h> int wctomb_l(char *s, wchar_t wchar, locale_t loc); DESCRIPTION The wctomb() function converts a wide character, wchar, into a multibyte character and stores the result in s. The object pointed to by s must be large enough to accommodate the multibyte character, which may be up to MB_LEN_MAX bytes. A call with a null s pointer returns nonzero if the current locale requires shift states, zero otherwise; if shift states are required, the shift state is reset to the initial state. Although the wctomb() function uses the current locale, the wctomb_l() function may be passed a locale directly. See xlocale(3) for more infor-mation. information. mation. RETURN VALUES If s is NULL, the wctomb() function returns nonzero if shift states are supported, zero otherwise. If s is valid, wctomb() returns the number of bytes processed in s, or -1 if no multibyte character could be recognized or converted. In this case, wctomb()'s internal conversion state is undefined. ERRORS The wctomb() function will fail if: [EILSEQ] An invalid multibyte sequence was detected. [EINVAL] The internal conversion state is invalid. SEE ALSO mbtowc(3), wcrtomb(3), wcstombs(3), wctob(3), xlocale(3) STANDARDS The wctomb() function conforms to ISO/IEC 9899:1999 (``ISO C99''). BSD April 8, 2004 BSD |
