explain_iconv_close_or_die - deallocate conversion descriptor and report errors
#include <libexplain/iconv_close.h>
void explain_iconv_close_or_die(iconv_t cd);
int explain_iconv_close_on_error(iconv_t cd);
The explain_iconv_close_or_die function is used to call the iconv_close(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_iconv_close(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_iconv_close_on_error function is used to call the iconv_close(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_iconv_close(3) function, but still returns to the caller.
The explain_iconv_close_or_die function only returns on success, see iconv_close(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_iconv_close_on_error function always returns the value return by the wrapped iconv_close(3) system call.
The explain_iconv_close_or_die function is intended to be used in a fashion similar to the following example:
explain_iconv_close_or_die(cd);
