ICONV_OPEN (3)
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 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.
The resulting conversion descriptor can be used with iconv any number
of times. It remains valid until deallocated using iconv_close.
A conversion descriptor contains a conversion state. After creation using
iconv_open, the state is in the initial state. Using iconv
modifies the descriptor's conversion state. (This implies that a conversion
descriptor can not be used in multiple threads simultaneously.) To bring the
state back to the initial state, use iconv with NULL as inbuf
argument.
RETURN VALUE
The iconv_open function returns a freshly allocated conversion
descriptor. In case of error, it sets errno and returns (iconv_t)(-1).
ERRORS
The following error can occur, among others:
EINVAL
The conversion from fromcode to tocode is not supported by the
implementation.
