iconv_open(3)           Library Functions Manual           iconv_open(3)

ИМЯ

       iconv_open - allocate descriptor for character set conversion

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <iconv.h>

       iconv_t iconv_open(const char *tocode, const char *fromcode);

ОПИСАНИЕ

       The iconv_open() function allocates a conversion descriptor
       suitable for converting byte sequences from character encoding
       fromcode to character encoding tocode.

       The values permitted for fromcode and tocode and the supported
       combinations are system-dependent.  For the GNU C library, the
       permitted values are listed by the iconv --list command, and all
       combinations of the listed values are supported.  Furthermore the
       GNU C library and the GNU libiconv library support the following
       two suffixes:

       //TRANSLIT
              When the string "//TRANSLIT" is appended to tocode,
              transliteration is activated.  This means that when a
              character cannot be represented in the target character
              set, it can be approximated through one or several
              similarly looking characters.

       //IGNORE
              When the string "//IGNORE" is appended to tocode,
              characters that cannot be represented in the target
              character set will be silently discarded.

       The resulting conversion descriptor can be used with iconv(3) any
       number of times.  It remains valid until deallocated using
       iconv_close(3).

       A conversion descriptor contains a conversion state.  After
       creation using iconv_open(), the state is in the initial state.
       Using iconv(3) modifies the descriptor's conversion state.  To
       bring the state back to the initial state, use iconv(3) with NULL
       as inbuf argument.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, iconv_open() returns a freshly allocated conversion
       descriptor.  On failure, it returns (iconv_t) -1 and sets errno
       to indicate the error.

ОШИБКИ

       The following error can occur, among others:

       EINVAL The conversion from fromcode to tocode is not supported by
              the implementation.
