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 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).
