If conversion -stops because a null character is encountered, *<[src]> is set to NULL. - -The mbstate_t argument, <[ps]>, is used to keep track of the shift state. If -it is NULL, <<wcsrtombs>> uses an internal, static mbstate_t object, which -is initialized to the initial conversion state at program startup. - -The <<wcsnrtombs>> function behaves identically to <<wcsrtombs>>, except that -conversion stops after reading at most <[nwc]> characters from the buffer -pointed to by <[src]>. - -RETURNS -The <<wcsrtombs>> and <<wcsnrtombs>> functions return the number of bytes -stored in the array pointed to by <[dst]> (not including any terminating -null), if successful, otherwise it returns (size_t)-1. - -PORTABILITY -<<wcsrtombs>> is defined by C99 standard. -<<wcsnrtombs>> is defined by the POSIX.1-2008 standard. -*/ - -#include <reent.h> -#include <newlib.h> -#include <wchar.h> -#include <stdlib.h> -#include <stdio.h> -#include <errno.h> -#include "local.h" - -size_t -_DEFUN (_wcsnrtombs_r, (r, dst, src, nwc, len, ps), - struct _reent *r _AND - char *dst _AND - const wchar_t **src _AND - size_t nwc _AND - size_t len _AND - mbstate_t *ps) -{ - char *ptr = dst; - char buff[10]; - wchar_t *pwcs; - size_t n; - int i; - -#ifdef _MB_CAPABLE - if (ps == NULL) - { - _REENT_CHECK_MISC(r); - ps = &(_REENT_WCSRTOMBS_STATE(r)); - } -#endif - - /* If no dst pointer, treat len as maximum possible value. */ - if (dst == NULL) - len = (size_t)-1; - - n = 0; - pwcs = (wchar_t *)(*src); - - while (n < len && nwc-- > 0) - { - int count = ps->__count; - wint_t wch = ps->__value.__wch; - int bytes = __wctomb (r, buff, *pwcs, __locale_charset (), ps); - if (bytes == -1) - { - r->_errno = EILSEQ; - ps->__count = 0; - return (size_t)-1; - } - if (n + bytes <= len) - { - n += bytes; - if (dst) - { - for (i = 0; i < bytes; ++i) - *ptr++ = buff[i]; - ++(*src); - } - if (*pwcs++ == 0x00) - { - if (dst) - *src = NULL; - ps->__count = 0; - return n - 1; - } - } - else - { - /* not enough room, we must back up state to before __wctomb call */ - ps->__count = count; - ps->__value.__wch = wch; - len = 0; - } - } - - return n; -} - -#ifndef _REENT_ONLY -size_t -_DEFUN (wcsnrtombs, (dst, src, nwc, len, ps), - char *dst _AND - const wchar_t **src _AND - size_t nwc _AND - size_t len _AND - mbstate_t *ps) -{ - return _wcsnrtombs_r (_REENT, dst, src, nwc, len, ps); -} -#endif /* !_REENT_ONLY */ |
