SYNOPSIS

11       iconv_t explain_iconv_open_or_die(const char *tocode, const char *from‐
12       code);
13       iconv_t  explain_iconv_open_on_error(const  char  *tocode,  const  char
14       *fromcode);

DESCRIPTION

17       The  explain_iconv_open_or_die   function   is   used   to   call   the
18       iconv_open(3) system call. On failure an explanation will be printed to
19       stderr, obtained from the explain_iconv_open(3) function, and then  the
20       process terminates by calling exit(EXIT_FAILURE).
21
22       The   explain_iconv_open_on_error   function   is   used  to  call  the
23       iconv_open(3) system call. On failure an explanation will be printed to
24       stderr,  obtained  from  the  explain_iconv_open(3) function, but still
25       returns to the caller.
26
27       tocode  The tocode, exactly as to be passed to the iconv_open(3) system
28               call.
29
30       fromcode
31               The fromcode, exactly as to be passed to the iconv_open(3) sys‐
32               tem call.

37       and exits, it does not return.

40       return by the wrapped iconv_open(3) system call.
