The result of the call is -to create a conversion specifier that can be used with <<iconv>>. - -The function <<iconv_close>> is used to close a conversion specifier after -it is no longer needed. - -The <<_iconv_r>>, <<_iconv_open_r>>, and <<_iconv_close_r>> functions are -reentrant versions of <<iconv>>, <<iconv_open>>, and <<iconv_close>>, -respectively. An additional reentrancy struct pointer: <[rptr]> is passed -to properly set <<errno>>. - -RETURNS -The <<iconv>> function returns the number of non-identical conversions -performed. If an error occurs, (size_t)-1 is returned and <<errno>> -is set appropriately. The values of <[inleft]>, <[in]>, <[out]>, -and <[outleft]> are modified to indicate how much input was processed -and how much output was created. - -The <<iconv_open>> function returns either a valid conversion specifier -or (iconv_t)-1 to indicate failure. If failure occurs, <<errno>> is set -appropriately. - -The <<iconv_close>> function returns 0 on success or -1 on failure. -If failure occurs <<errno>> is set appropriately. - -PORTABILITY -<<iconv>>, <<iconv_open>>, and <<iconv_close>> are non-ANSI and are specified -by the Single Unix specification. - -No supporting OS subroutine calls are required. -*/ -#include <_ansi.h> -#include <reent.h> -#include <sys/types.h> -#include <errno.h> -#include <string.h> -#include <stdlib.h> -#include <iconv.h> -#include <wchar.h> -#include <sys/iconvnls.h> -#include "local.h" -#include "conv.h" -#include "ucsconv.h" - -/* - * iconv interface functions as specified by Single Unix specification. - */ - -iconv_t -_DEFUN(iconv_open, (to, from), - _CONST char *to _AND - _CONST char *from) -{ - return _iconv_open_r (_REENT, to, from); -} - - -size_t -_DEFUN(iconv, (cd, inbuf, inbytesleft, outbuf, outbytesleft), - iconv_t cd _AND - _CONST char **inbuf _AND - size_t *inbytesleft _AND - char **outbuf _AND - size_t *outbytesleft) -{ - return _iconv_r (_REENT, cd, inbuf, inbytesleft, outbuf, outbytesleft); -} - - -int -_DEFUN(iconv_close, (cd), iconv_t cd) -{ - return _iconv_close_r (_REENT, cd); -} - - -#ifndef _REENT_ONLY -iconv_t -_DEFUN(_iconv_open_r, (rptr, to, from), - struct _reent *rptr _AND - _CONST char *to _AND - _CONST char *from) -{ - iconv_conversion_t *ic; - - if (to == NULL || from == NULL || *to == '\0' || *from == '\0') - return (iconv_t)-1; - - if ((to = (_CONST char *)_iconv_resolve_encoding_name (rptr, to)) == NULL) - return (iconv_t)-1; - - if ((from = (_CONST char *)_iconv_resolve_encoding_name (rptr, from)) == NULL) - { - _free_r (rptr, (_VOID_PTR)to); - return (iconv_t)-1; - } - - ic = (iconv_conversion_t *)_malloc_r (rptr, sizeof (iconv_conversion_t)); - if (ic == NULL) - return (iconv_t)-1; - - /* Select which conversion type to use */ - if (strcmp (from, to) == 0) - { - /* Use null conversion */ - ic->handlers = &_iconv_null_conversion_handlers; - ic->data = ic->handlers->open (rptr, to, from); - } - else - { - /* Use UCS-based conversion */ - ic->handlers = &_iconv_ucs_conversion_handlers; - ic->data = ic->handlers->open (rptr, to, from); - } - - _free_r (rptr, (_VOID_PTR)to); - _free_r (rptr, (_VOID_PTR)from); - - if (ic->data == NULL) - { - _free_r (rptr, (_VOID_PTR)ic); - return (iconv_t)-1; - } - - return (_VOID_PTR)ic; -} - - -size_t -_DEFUN(_iconv_r, (rptr, cd, inbuf, inbytesleft, outbuf, outbytesleft), - struct _reent *rptr _AND - iconv_t cd _AND - _CONST char **inbuf _AND - size_t *inbytesleft _AND - char **outbuf _AND - size_t *outbytesleft) -{ - iconv_conversion_t *ic = (iconv_conversion_t *)cd; - - if ((_VOID_PTR)cd == NULL || cd == (iconv_t)-1 || ic->data == NULL - || (ic->handlers != &_iconv_null_conversion_handlers - && ic->handlers != &_iconv_ucs_conversion_handlers)) - { - __errno_r (rptr) = EBADF; - return (size_t)-1; - } - - if (inbuf == NULL || *inbuf == NULL) - { - mbstate_t state_null = ICONV_ZERO_MB_STATE_T; - - if (!ic->handlers->is_stateful(ic->data, 1)) - return (size_t)0; - - if (outbuf == NULL || *outbuf == NULL) - { - /* Reset shift state */ - ic->handlers->set_state (ic->data, &state_null, 1); - - return (size_t)0; - } - - if (outbytesleft != NULL) - { - mbstate_t state_save = ICONV_ZERO_MB_STATE_T; - - /* Save current shift state */ - ic->handlers->get_state (ic->data, &state_save, 1); - - /* Reset shift state */ - ic->handlers->set_state (ic->data, &state_null, 1); - - /* Get initial shift state sequence and it's length */ - ic->handlers->get_state (ic->data, &state_null, 1); - - if (*outbytesleft >= state_null.__count) - { - memcpy ((_VOID_PTR)(*outbuf), (_VOID_PTR)&state_null, state_null.__count); - - *outbuf += state_null.__count; - *outbytesleft -= state_null.__count; - - return (size_t)0; - } - - /* Restore shift state if output buffer is too small */ - ic->handlers->set_state (ic->data, &state_save, 1); - } - - __errno_r (rptr) = E2BIG; - return (size_t)-1; - } - - if (*inbytesleft == 0) - { - __errno_r (rptr) = EINVAL; - return (size_t)-1; - } - - if (*outbytesleft == 0 || *outbuf == NULL) - { - __errno_r (rptr) = E2BIG; - return (size_t)-1; - } - - return ic->handlers->convert (rptr, - ic->data, - (_CONST unsigned char**)inbuf, - inbytesleft, - (unsigned char**)outbuf, - outbytesleft, - 0); -} - - -int -_DEFUN(_iconv_close_r, (rptr, cd), - struct _reent *rptr _AND - iconv_t cd) -{ - int res; - iconv_conversion_t *ic = (iconv_conversion_t *)cd; - - if ((_VOID_PTR)cd == NULL || cd == (iconv_t)-1 || ic->data == NULL - || (ic->handlers != &_iconv_null_conversion_handlers - && ic->handlers != &_iconv_ucs_conversion_handlers)) - { - __errno_r (rptr) = EBADF; - return -1; - } - - res = (int)ic->handlers->close (rptr, ic->data); - - _free_r (rptr, (_VOID_PTR)cd); - - return res; -} -#endif /* !_REENT_ONLY */ |
