NAME

explain_iconv_or_die - perform character set conversion and report errors

SYNOPSIS

#include <libexplain/iconv.h>

size_t explain_iconv_or_die(iconv_t cd, char **inbuf, size_t *inbytesleft, char **outbuf, size_t *outbytesleft);
size_t explain_iconv_on_error(iconv_t cd, char **inbuf, size_t *inbytesleft, char **outbuf, size_t *outbytesleft);

DESCRIPTION

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

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

cd: The cd, exactly as to be passed to the iconv(3) system call.
inbuf: The inbuf, exactly as to be passed to the iconv(3) system call.
inbytesleft: The inbytesleft, exactly as to be passed to the iconv(3) system call.
outbuf: The outbuf, exactly as to be passed to the iconv(3) system call.
outbytesleft: The outbytesleft, exactly as to be passed to the iconv(3) system call.

RETURN VALUE

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

The explain_iconv_on_error function always returns the value return by the wrapped iconv(3) system call.

EXAMPLE

The explain_iconv_or_die function is intended to be used in a fashion similar to the following example:

size_t result = explain_iconv_or_die(cd, inbuf, inbytesleft, outbuf,
    outbytesleft);
