NAMEiconv_open - allocate descriptor for character set conversion
#include <iconv.h>iconv_t iconv_open(const char *tocode, const char *fromcode);
DESCRIPTIONThe 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:
- 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.
- When the string "//IGNORE" is appended to tocode, characters that cannot be represented in the target character set will be silently discarded.
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 VALUEThe iconv_open() function returns a freshly allocated conversion descriptor. In case of error, it sets errnoand returns (iconv_t) -1.
ERRORSThe following error can occur, among others:
- The conversion from fromcodeto tocodeis not supported by the implementation.
VERSIONSThis function is available in glibc since version 2.1.
