NAME
iconvctl - control iconv behavior SYNOPSIS
#include <iconv.h> int iconvctl (iconv_t cd , int request, void * argument); DESCRIPTION
The argument cd must be a conversion descriptor created using the function iconv_open. iconvctl queries or adjusts the behavior of the iconv function, when invoked with the specified conversion descriptor, depending on the request value. REQUEST VALUES
The following are permissible values for the request parameter. ICONV_TRIVIALP argument should be an int * which will receive 1 if the conversion is trivial, or 0 otherwise. ICONV_GET_TRANSLITERATE argument should be an int * which will receive 1 if transliteration is enabled in the conversion, or 0 otherwise. ICONV_SET_TRANSLITERATE argument should be a const int *, pointing to an int value. A non-zero value is used to enable transliteration in the conversion. A zero value disables it. ICONV_GET_DISCARD_ILSEQ argument should be an int * which will receive 1 if "illegal sequence discard and continue" is enabled in the conversion, or 0 oth- erwise. ICONV_SET_DISCARD_ILSEQ argument should be a const int *, pointing to an int value. A non-zero value is used to enable "illegal sequence discard and con- tinue" in the conversion. A zero value disables it. RETURN VALUE
The iconvctl function returns 0 if it succeeds. In case of error, it sets errno and returns -1. ERRORS
The following errors can occur, among others: EINVAL The request is invalid. CONFORMING TO
This function is implemented only in GNU libiconv and not in other iconv implementations. It is not backed by a standard. You can test for its presence through (_LIBICONV_VERSION >= 0x0108). SEE ALSO

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 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 repre- sented 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. (This implies that a conversion descriptor can not be used in multiple threads simultane- ously.) To bring the state back to the initial state, use iconv(3) 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. VERSIONS
This function is available in glibc since version 2.1. CONFORMING TO
