 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:
