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 func-
tion 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 conver-
sion is trivial, or 0 otherwise.
ICONV_GET_TRANSLITERATE
argument should be an int * which will receive 1 if translitera-
tion 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 conver-
sion. 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 otherwise.
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
continue" 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).
