If the translation type is invalid or cannot be applied to the current character, no change to the character is made. RETURNS <<towctrans>> returns the translated equivalent of <[c]> when it is a valid for the given translation, otherwise, it returns the input character. When the translation type is invalid, <<errno>> is set <<EINVAL>>. PORTABILITY <<towctrans>> is C99. No supporting OS subroutines are required. */ #include <_ansi.h> #include <string.h> #include <reent.h> #include <wctype.h> #include <errno.h> #include "local.h" wint_t _DEFUN (_towctrans_r, (r, c, w), struct _reent *r _AND wint_t c _AND wctrans_t w) { if (w == WCT_TOLOWER) return towlower (c); else if (w == WCT_TOUPPER) return towupper (c); else { r->_errno = EINVAL; return c; } } #ifndef _REENT_ONLY wint_t _DEFUN (towctrans, (c, w), wint_t c _AND wctrans_t w) { return _towctrans_r (_REENT, c, w); } #endif /* !_REENT_ONLY */
