NAME

iconv_open - allocate descriptor for character set conversion  

SYNOPSIS

#include <iconv.h>iconv_t iconv_open(const char *tocode, const char *fromcode);
 

DESCRIPTION

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

The values permitted for fromcodeand tocodeand the supported combinations are system-dependent. For the GNU C library, the permitted values are listed by the iconv --listcommand, 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 inbufargument.  

RETURN VALUE

The iconv_open() function returns a freshly allocated conversion descriptor. In case of error, it sets errnoand returns (iconv_t) -1.  

ERRORS

The following error can occur, among others:
EINVAL
The conversion from fromcodeto tocodeis not supported by the implementation.
 

VERSIONS

This function is available in glibc since version 2.1.
