NAME

       explain_iconv_open_or_die - prepare for charset conversion and report errors

SYNOPSIS

       #include <libexplain/iconv_open.h>
       iconv_t explain_iconv_open_or_die(const char *tocode, const char *fromcode);
       iconv_t explain_iconv_open_on_error(const char *tocode, const char *fromcode);

DESCRIPTION

       The  explain_iconv_open_or_die  function is used to call the iconv_open(3) system call. On
       failure an explanation will be printed to stderr, obtained from the  explain_iconv_open(3)
       function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_iconv_open_on_error function is used to call the iconv_open(3) system call. On
       failure an explanation will be printed to stderr, obtained from the  explain_iconv_open(3)
       function, but still returns to the caller.

       tocode  The tocode, exactly as to be passed to the iconv_open(3) system call.

       fromcode
               The fromcode, exactly as to be passed to the iconv_open(3) system call.

RETURN VALUE

       The explain_iconv_open_or_die function only returns on success, see iconv_open(3) for more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_iconv_open_on_error function always returns the value return  by  the  wrapped
       iconv_open(3) system call.

EXAMPLE

       The  explain_iconv_open_or_die function is intended to be used in a fashion similar to the
       following example:
              iconv_t result = explain_iconv_open_or_die(tocode, fromcode);
